Hi, all. I'm a US citizen who recently submitted Form I-130 for my Filipina spouse (although the overseas country shouldn't matter much for this discussion). Given the insane two- to three-year waits that seem to be inevitable before her visa interview, I decided to move to the Philippines to live with her for the time being. Finances are not an issue and I have nothing tying me to the US. My plan once I get to the Philippines is to rent a house or an apartment with her jointly in order to begin gathering co-mingling evidence. I'll apply for an ACR-I card as soon as possible, then apply for a 13(a) visa so that I am able to legally work, own property, etc. (things that can't be done on a non-immigrant visa). While there, I plan on saving every receipt, ticket, itinerary, photo, etc. that can be used as evidence during the visa interview. For employment, she and I are going to start an online business based in the US that should be usable during the visa interview to prove support of beneficiary and also intent to re-domicile, which seem to be two problems people commonly run into during that stage. We also plan on taking a motorcycle driving course and buying a motorcycle.
My question for the experienced people here: What else should I focus on gathering or doing to ensure the visa interview goes as smoothly as possible?
