Portugal’s Agency for Integration, Migration and Asylum (AIMA) has advised residency applicants and renewals to pay close attention to file naming. Clear and simple file names help reduce technical errors and speed up document processing. The agency recommends using short names without accents, special characters, or complex symbols. If uploads fail, applicants are encouraged to try a different browser. AIMA suggests using “passaporte.pdf” for passport scans and “titulo.pdf” or “CartaoResidencia.pdf” for residence cards. Applicants are also advised to double-check file names before submission. Material taken from https://xn--r1a.website/s/portugalpages
