Round 1: Getting in
Draw
Doha: visa-free on a passport. No visa needed; a permit issued on arrival allows a stay of 90 days for tourism or business. Passport valid over six months with two blank pages. Dubai: visa-free on a passport. Portuguese citizens receive a 90-day short-stay authorisation on arrival, usable as 90 days in any 180-day period; passport valid six months; temporary passports are not accepted. Identical: a 90-day permit on arrival for Portuguese citizens in both, no visa. Dubai does not accept temporary passports; Doha wants two blank pages.
Rule: Fewer hoops wins: ID card, then visa-free, then on-arrival permit, then e-visa, then consular visa.
