Which countries recognize same-sex marriage for spousal visas?

The short answer: of the nine countries we track, eight recognize a US same-sex marriage as a marriage for immigration purposes without qualification — your spouse rides your visa, or sponsors you, exactly as any spouse would. The ninth, Italy, admits your spouse too, but converts the marriage into a civil union on paper. The differences that actually decide cases sit one level down: income uplifts, filing sequence, and how far recognition reaches beyond the visa itself. Answer current as of November 6, 2026.

The headline map, dated

Marriage equality now covers all nine countries on our list except Italy: the Netherlands wrote the template in 2001, Spain followed in 2005, Portugal in 2010, France in 2013, and the UK in 2014; Mexico completed nationwide coverage in October 2022 (federal recognition follows the marriage, not the state), Greece arrived in February 2024 with retroactive recognition of marriages performed abroad, and Thailand in January 2025 became Asia's first. In all eight, the marriage certificate from your American courthouse is the operative document for spousal immigration — apostilled, sometimes transcribed, never second-guessed as to the spouses' sexes.

What recognition actually buys, per country

The uplift countries. Portugal and Greece attach a spouse to the principal's visa by an income uplift: Portugal's D7 adds 50% of the minimum wage for a spouse, and its D8 lets a spouse either ride as family or file as a second principal (a choice with real consequences we cover in a separate note); Greece brings family in by uplift on the nomad route. Portugal's practical rule, confirmed by Lisbon counsel: file together at the consulate — sequencing a spouse "later" is now the slower, riskier shape. Spain runs spousal recognition through both its national routes and the EU family framework; a same-sex spouse is a spouse everywhere in the system, as you'd expect from the world's third marriage-equality country. The Netherlands recognizes marriages and durable partnerships on both partner tracks. France gives the spouse of a French citizen a vie privée et familiale card with immediate work rights — after the US marriage is transcribed into French civil records via the consulate, a step Americans routinely discover late. The UK recognizes the marriage without blinking but prices the route: the Appendix FM spouse visa requires sponsor income of £29,000, a figure frozen while the government decides whether to lower it — and the sponsor must be settled; two Americans moving together use other routes, with the spouse as dependent. Mexico ties residency to the marriage directly: spouse of a Mexican national or of a resident qualifies for temporary residency, exchangeable for permanent after two years. Thailand is the newest and worth stating precisely: same-sex spouses qualify in practice, not just on paper — immigration implemented the pathways in March 2025, foreign marriage certificates are accepted for the 90-day entry, and the one-year in-country extension requires registering the foreign marriage at a district office. Thailand's long-term resident visa likewise now counts same-sex spouses among dependents, with no cap.

Italy, honestly

Italy will admit your spouse — but not your marriage. A US same-sex marriage is downgraded to a civil union on transcription; that union opens the family permit and, with an Italian-citizen partner, a genuinely fast citizenship track. And where EU law applies, the Coman doctrine forces the point: Italy must grant residence to the same-sex spouse of an EU citizen even though its own law won't call the relationship a marriage. For pure immigration mechanics, Italy works. For everything the word marriage touches beyond the visa — parentage above all — Italy is the file where we tell clients to structure the legal family before arrival, not after.

What this means for your plan

Recognition is the solved layer; read the fine print on what it's attached to. Check the income math your spouse adds (an uplift in Portugal and Greece, a sponsor threshold in the UK, independent files where both partners work). Check the sequence — file together in Portugal, transcribe first in France, register locally for Thailand's extension. And check the reach — a visa that recognizes your marriage is not the same as a legal system that recognizes everything your marriage contains, which is why Italy sits apart and why parentage gets its own note. If you're unmarried, the map redraws entirely — that note is here.
