I'm a US citizen, wife is a Hungarian citizen. I am domiciled in the US but living with her in Hungary for the time being. We will submit the IR-1 application but since it is taking like 14-15 months (from what I've read), we would like to enter the US sooner. Per the B-1 rules she can stay up to 6 months in the US. Based on the usual timeline, it seems like we will be in the US when it comes time for her consular interview, back in Hungary.
Instead of flying all the way back to Hungary, just to do the interview, and, I guess, wait a few more months for approval, will USCIS let her do the interview in the States? And yes, I understand that you cannot enter on a B-1 visa with the intention to stay. She has ties to Hungary.
