Exact AIMA route and duration
An EU/EEA student staying beyond three months requests the CRUE from the local Câmara Municipal within 30 days after the first three months. It is separate from NIF and tax residence. A pre-arrival NIF is normally registered as non-resident and must be updated when the facts change.
For Article 91, prepare passport, residence visa unless the lawful no-visa route applies, legal-entry evidence, a housing declaration supported by the right to occupy, means, criminal record from nationality/previous residence over one year, enrolment, tuition evidence where applicable, and insurance or SNS coverage. The higher-education permit is normally valid for three years, renewable for equal periods, or for the course length when shorter. Approved institutions and Camões scholarships have specific waivers; do not generalise them. Article 91(4) still requires lawful entry/stay and every other condition. The permit allows employed or independent activity only as complementary to study.
How to manage a practice without losing control
Treat each application as an evidentiary file. Create an index with requirement, document, issuing authority, date, translation and page. Before sending, compare your passport, form, CV, offer/CoE and previous entries: names, dates and activities must tell the same story. If an answer does not fit the field, attach a numbered note that specifically addresses the question. Don’t upload dozens of files without explanation or rename a document in a deceptive way.
Keep an immutable copy of the submitted package and a separate working folder. Record receipt, application number, deadlines and messages. Communications often arrive in the portal before the email; check it regularly. A request for information should not be construed as a refusal, but the response must be complete, timely and to the point. If you can’t get a document, demonstrate attempts and ask for instructions - don’t invent substitutes.
When you really need a professional
A standard, documented case can be handled by reading the official instructions. Seek regulated advice when you have refusals or cancellations, unlawful status, criminal record, relevant medical conditions, complex family members, incorrect information already submitted, material change of route or imminent deadlines. Verify license and identity in the official register, sign a written engagement with scope, fees and document management and pay on a verified professional account.
Ask the advisor to distinguish law, policy, practice and your risk assessment. No one can guarantee concession or timing. Maintain access to the portal and receive a copy of every communication. If a strategy requires omitting a fact, creating a relationship or showing money that isn’t actually available, stop: the risk of false information can outweigh the problem you wanted to hide.
Final check before each shipment
Reread the question as a decision maker who doesn’t know you. Check validity of passport, quality of scans, translations, signature, payment and deadline time zone. Check that links and contacts are official, that the card allows the operation and that the receipt is saved. After submitting, do not change your life based solely on the expectation of approval: maintain existing status, registration, insurance and conditions until a new decision produces effects.
