I am a male Chinese ,my bf is American ,if we marry can i get USA passport ? thx?

you get a green card first ...then 3 year as later you can apply for citizenship BUT you lose the Chinese one,,, the Chinese do not allow dual

No, marriage doesn't get you citizenship and only citizens can get a passport, marriage doesn't even give you a right to live in the country, your bf will have to sponsor a visa for you to do that

no

In America, it's LEGAL for same sex to get married. Why would you not be able to get a passport because of it?

You will have to get a US fiancee work visa

US passports are only for Americans

You will have to have a passport to come here

If you're gay then they won't let it happen

No.
