D4 Student / Research visa

The D4 visa covers residence for study, student exchange, scientific research, professional internship and volunteering in Portugal. The fundamental requirement is an acceptance letter or proof of enrolment at a recognised Portuguese higher education institution, or a research protocol with a recognised scientific institution.

Financially, you must show sufficient means of subsistence: a scholarship certificate (Portuguese Government scholars are exempt from other financial proof), a letter of financial responsibility from a family member, or proof of own income. Health insurance for the full period is mandatory. The consular fee is €90 (exempt for scholarship holders). VFS Global processing takes 60–90 days.

Doctoral and post-doctoral students affiliated with a recognised research institution may qualify for the D3 (highly qualified) route instead, which offers consular fee exemption and more favourable conditions. D4 visa holders may work part-time (up to 20 hours per week) during the academic term, which helps cover living costs.

Confirm the specific requirements of your institution and consulate before applying.
