What documents does a foreign worker need to work in Portugal?

Who can apply for Job On vacancies

For jobs in Portugal, you need to already live in Portugal with one of these documents: Portuguese or other EU citizenship, a valid residence permit (TRC), or a residence permit being renewed, with proof from AIMA. With a visa or an expression of interest we cannot place you yet. Job On does not handle visa applications.

For jobs in other European countries, each vacancy says what it requires: you need the right to work in the EU, through citizenship of an EU country or a residence permit in an EU country.

The numbers you will need

In some cases these numbers can be requested together in a single application. Check the gov.pt portal to see whether your situation qualifies.

• NIF (tax identification number): issued by the tax office, Finanças. You need it to be paid, pay tax and open a bank account
• NISS (social security number): issued by Segurança Social. It records your contributions and gives you access to benefits such as sick pay
• SNS user number: issued by your local health centre, so you can use the national health service

If you are an EU citizen

Citizens of the European Union, the European Economic Area and Switzerland can work in Portugal without a visa, using their ID card or passport. If you stay in Portugal for more than three months, you apply for an EU citizen registration certificate at the town hall where you live.

If you come from outside the EU

You need a permit that allows you to work in Portugal: a suitable visa, such as a work visa, or a residence permit that allows you to take up employment. Your NIF and NISS go alongside that permit, which is what lets you sign a legal employment contract.

Visas are requested at Portuguese consulates in your country. Residence permits are handled by AIMA, the Agency for Integration, Migration and Asylum, which replaced SEF in October 2023.

If you are already in Portugal with a residence permit, check that it allows you to work as an employee and that it is still valid.

When we talk to you about a job, we explain which documents that placement needs and help you get your paperwork in order. Your temporary employment contract is always in writing and signed with Job On, and you always have someone to ask.

Before you accept a job offer, check that it comes from a licensed temporary work agency. Applying to Job On is always free, from your first message to your contract.
