Working Part-Time on a Student Visa (Article 97): Rules and Approvals

Struggling to balance the high cost of rent in Lisbon with a student budget is a rite of passage that feels more like a marathon. I remember staring at my bank balance in a Chiado cafe, realizing my savings were dwindling faster than my patience with the local bureaucracy. This guide solves the mystery of Article 97, detailing exactly how you can legally work part-time in Portugal while maintaining your student status.

Understanding Article 97 of the Foreigners Law

The legal framework governing your right to work as a non-EU student is found in Article 97 (Artigo 97) of the Portuguese Law on Foreigners. For many of us arriving from outside the Schengen area, the initial assumption is that a student visa is strictly for the classroom. However, Portugal is surprisingly progressive in this regard, recognizing that international talent often needs to supplement their income to survive and thrive.

What is Artigo 97 and Who Does It Cover

Artigo 97 specifically addresses the "Exercise of professional activity by holders of a residence permit for study, secondary education, internship or volunteer work." In plain English, this means if you hold a valid residence permit for a higher education program (Bachelors, Masters, or PhD), you are legally entitled to work. The law was designed to allow students to integrate into the local labor market without abandoning their primary purpose of being here: their education.

When I first looked into this, I was worried about whether my specific course qualified. Generally, if your university is recognized by the Ministry of Science, Technology and Higher Education, you fall under this umbrella. It is not just about flipping burgers or pouring lattes; this article covers internships and professional roles that can kickstart your career. To make yourself more competitive in the local market, I found that using resources like PortuguesePod101 helped me bridge the gap between "classroom Portuguese" and "office Portuguese" much faster.

The Shift from SEF to AIMA

You will likely hear veteran expats grumbling about "SEF," the old immigration service. As of late 2023 and into 2026, those responsibilities have shifted to AIMA (Agência para a Integração, Migrações e Asilo). This is a crucial distinction because your rights under Article 97 must be communicated to AIMA. The law hasn't changed, but the portal and the faces behind the desk have.

Understanding this transition is vital for your peace of mind. While the backlog at AIMA is a frequent topic of conversation in expat Facebook groups, your right to work is protected as long as you follow the notification procedures. If you are just starting your journey, you should review the Portugal Visa and Immigration Guide for Expats: The Complete 2027 Overview to see how Article 97 fits into the broader residency landscape.

Essential Requirements Before You Start Working

Before you sign an employment contract or start your first shift at a tech startup in Porto, there are a few administrative hurdles you must clear. You cannot simply show your student card to an employer and call it a day. In Portugal, the "Paperwork Trinity"—the NIF, the NISS, and the AIMA notification—is non-negotiable.

Getting Your NIF and NISS

The NIF (Número de Identificação Fiscal) is your tax identification number, and it is the first thing you need for everything from getting a SIM card to renting an apartment. As a student, you likely already have one, but if you don't, you'll need a fiscal representative if you are from outside the EU. Once you have a job offer, you will also need a NISS (Número de Identificação da Segurança Social).

Employers in Portugal are quite strict about the NISS because they are legally required to pay social security contributions on your behalf. Students who don't have these numbers ready can lose out on great opportunities. For a detailed breakdown of the steps, check out NIF and NISS: How to Get Your Portuguese Tax and Social Security Numbers. Having these in hand makes you look much more "employable" to a Portuguese HR manager who might be hesitant about the paperwork involved in hiring a non-EU citizen.

Notifying AIMA and the Approval Process

One of the most misunderstood parts of Article 97 is the "authorization" versus "notification" aspect. Under the current law, you do not necessarily need to wait for a new residence card that explicitly says "Authorized to Work." Instead, you (or your employer) must notify AIMA that you are engaging in professional activity.

This notification usually includes your employment contract, your current residence permit, and proof of enrollment at your university. The key is that the work activity must not interfere with your studies. If AIMA finds that you are working 40 hours a week and failing your classes, they have the right to revoke your permit. It’s a delicate balance. If you're feeling overwhelmed by the digital portals, AIMA Portugal: Navigating the New Immigration Agency and Residence Permits provides some much-needed clarity on navigating their often-finicky website.

Document Required	Purpose	Where to Obtain
Residence Permit (Title of Residence)	Proves your legal status in Portugal	AIMA

NISS (Social Security Number)	Required for social security contributions	Segurança Social
University Enrollment Proof	Confirms you are still a student	University Registrar
Employment Contract	Outlines hours, salary, and duties	Your Employer

Working Hours and Contract Types

A common question in the student community is: "How many hours can I actually work?" While many European countries have a hard cap of 20 hours per week, the Portuguese law is slightly more nuanced, focusing on the compatibility of work and study.

The 20-Hour Rule vs. Full-Time During Holidays

In practice, most student work is conducted as "part-time," which in Portugal typically means up to 20 or 24 hours per week. This is generally accepted as the limit that won't jeopardize your academic performance. However, Article 97 allows for more flexibility during university holidays. During the summer break (July and August) or the Christmas/Easter holidays, students are often permitted to work full-time.

Many students have worked 20 hours during the semester at a call center and then transitioned to 40 hours during the summer in the tourism sector in the Algarve. This is a great way to build up a financial cushion. Just remember that even if you're working in a high-paced environment, your language skills will be your biggest asset. Newcomers are often advised to spend 15 minutes a day on PortuguesePod101 to ensure they can handle the workplace banter and instructions from their "chefe."

Types of Employment Contracts for Students

You will likely encounter two main types of contracts: the Contrato de Trabalho (Standard Employment Contract) and the Recibos Verdes (Green Receipts/Freelancing). Most students preferred the standard contract because it offers more protections, such as paid vacation and a meal allowance.

The Contrato de Trabalho a Tempo Parcial (Part-time contract) is the most common for those covered by Article 97. It must be in writing and specify your hours. If a recruiter mentions a "cash-under-the-table" deal, walk away. Not only is it illegal, but it also provides zero evidence of your integration into the Portuguese system, which you will need if you eventually want to apply for permanent residency.

Taxes, Social Security, and Net Pay

The "sticker price" of your salary in Portugal is rarely what hits your bank account. As a working student, you are subject to the same tax and social security system as any other worker, though your lower total income might put you in a lower tax bracket.

Income Tax (IRS) and Withholding

In Portugal, income tax is called IRS. Your employer will usually withhold a percentage of your salary every month. Since the Minimum Wage (€920) vs Average Salary: What to Expect in Portugal is the benchmark for many part-time roles, your withholding rate might be quite low, or even zero if you earn below a certain annual threshold.

However, you still have to file an annual tax return (Modelo 3). This was the most confusing part for me. I spent hours trying to figure out why I was paying tax on a part-time wage. The good news is that if you are a student, there are certain deductions you can claim for education expenses that might result in a tax refund. It is worth the headache of learning the Portal das Finanças system just for that potential "reembolso" in June.

Social Security Contributions

Both you and your employer will contribute to Social Security. Typically, the employee's share is 11% of the gross salary. This deduction is mandatory and gives you access to the public healthcare system (SNS) and contributes to your "time served" in the system.

Being in the Social Security system is actually a benefit for students. It makes it much easier to prove you are a contributing member of society when it comes time to renew your residence permit. Just make sure your employer is actually making these payments; you can check your "Carreira Contributiva" on the Social Security Directa website. If you are thinking about your future after school, Converting a student residence permit to a work permit at AIMA is a logical next step to research once you are comfortably employed.

Challenges and Cultural Nuances

Working while studying in a foreign country isn't just about the laws; it's about the lifestyle. Portuguese universities are notoriously demanding, and the "Bologna Process" means you have a lot of continuous assessment.

Balancing University and Work

The "Student-Worker" (Estatuto Trabalhador-Estudante) is a legal status you can request at your university if you work a certain number of hours. This status is a lifesaver. It can grant you flexibility with exam dates, the right to miss a certain number of classes, and even special exam seasons.

When I was studying in Lisbon, I didn't realize I had to apply for this status at the beginning of the semester. I ended up struggling to balance a late-night shift with a 9:00 AM seminar. Don't make that mistake. Talk to your university's academic office as soon as you have your contract. They are used to international students working and will guide you through the internal requirements. To help you communicate these needs to your professors, a bit of extra study with PortuguesePod101 can give you the vocabulary to negotiate your schedule effectively.

Dealing with Employers and HR

Portuguese workplace hierarchy can be quite traditional. Even in modern tech hubs, there is a level of formality that might feel strange if you're coming from the US or Northern Europe. Using titles like "Sr." or "Dra." is common, and punctuality—while sometimes flexible in social settings—is strictly expected in professional ones.

You might also find that communication is more indirect. If an employer is unhappy with your hours, they might not tell you directly but rather "hint" at it. This is where your language skills and cultural awareness come in. If you are struggling to find a role, you might want to look into How to properly register at the IEFP office as an unemployed expat, although as a student, your primary resource will be the university job boards and LinkedIn. Make sure your CV follows local norms; Writing a CV for Portuguese Employers: Formats, Photos, and Cover Letters can help you stand out.

Transitioning After Graduation

The ultimate goal for many of us is to turn that part-time student job into a full-time career in Portugal. Article 97 is the stepping stone, but the transition to a full work permit (Article 88 or 89) requires careful timing.

From Student Visa to Work Permit

Once you have your diploma in hand, you are no longer a "student" in the eyes of the law, which means Article 97 no longer applies. You will need to apply for a "Change of Status" at AIMA. This is a common path, and as long as you have a full-time job offer that meets the salary requirements, it is generally a straightforward (if slow) process.

The advantage of having worked part-time during your studies is that you already have a NIF, a NISS, and a history with the tax authorities. This makes your application for a full work permit much stronger. You aren't a "new" arrival; you are an integrated resident. It’s also worth noting that Learning Portuguese for Career Growth: Certificates and Business Language is almost mandatory if you want to move into higher-paying management roles after graduation.

The Job Seeker Visa Option

If you graduate but don't have a job offer lined up immediately, Portugal offers a Job Seeker Visa. However, for those already in the country on a student permit, there is usually a "grace period" or a specific permit for looking for work after graduation.

This allows you to stay in Portugal for up to a year while you hunt for a role that matches your qualifications. During this time, the rules on working can be a bit of a gray area, so it's best to consult with a legal professional or a dedicated expat service. Most students I know used this time to polish their language skills using PortuguesePod101 and network like crazy at events in Parque das Nações or the various "incubadoras" around the city.

Important Considerations for Working Students

• University Attendance: Your priority must remain your studies. If your attendance drops, your university is obligated to report it, which can lead to the cancellation of your residence permit.
• Minimum Wage: Ensure you are being paid at least the proportional minimum wage for your hours. In 2026, the full-time minimum is €920.
• Insurance: Your employer's work accident insurance is mandatory. Make sure you are covered from day one.
• Renewals: When you renew your student residence permit, you will need to show that you are still successfully progressing in your studies, regardless of your work status.
• Language: While many tech jobs are in English, the "social glue" of the office is Portuguese. Investing time in PortuguesePod101 will pay dividends in how your colleagues perceive you.
