I am a US citizen, my husband is a German citizen and we live in Germany. I am going home in August to visit family, and then he was going to come in September and stay for 3 weeks. We have both been fully vaccinated and have all the paperwork to prove we're married. My question is, can he travel on his own and the relevant marriage paper work be enough to get him into the country, or is he only allowed in if I (the US citizen) am with him? Thanks for your help!
According to the relevant Presidential Proclamation:
(a) Section 1 of this proclamation shall not apply to:
(iii) any noncitizen who is the spouse of a U.S. citizen or lawful permanent resident;
There is no condition of residence or simultaneous travel.
Your husband will still require an ESTA (or other visa), and should have the required paperwork. Not sure exactly what paperwork, though, but I suppose some kind of proof of marriage + a copy of your US passport should do.
Note that I believe you will both need a recent negative PCR test even if fully vaccinated.
Please make sure he carries a copy of your wedding certificate and probably a copy of your passport. We ran into problems with my Swedish wife when we were boarding the plane in Zurich (layover airport). It ended up being a mad scramble to get someone to our house so we could prove we were married.
