How long can Americans stay in Portugal without a visa?
Updated · Applying from the US guide · Not legal advice
US citizens can visit Portugal and the rest of the Schengen area without a visa for up to 90 days in any 180-day period. That's for visits only: you can't stay on to live and work long-term, which is why the D8 is applied for from the US, and why you enter Portugal on the D8 visa itself before applying to AIMA.
| Item | Visa-free visit | D8 visa |
|---|---|---|
| Length | 90 days in any 180 (whole Schengen area) | Up to 12 months, or 4 months + residence permit |
| Remote work | Not a basis for living there | Yes, that's its purpose |
| Path to residence | No | Residence visa: yes |
Entry system changes
The EU's Entry/Exit System registers non-EU visitors' entries and exits electronically, and the EU plans ETIAS travel authorisation for visa-free visitors. Check the State Department's Portugal page before you travel.
The 90/180 rule
Look back 180 days from any day you're in the Schengen area: you may have been there no more than 90 of them. The European Commission has an official calculator.
