1. The grandfather does not have to come to the interview, correct?
2. We want to come for a visit for a few months to half a year (also for the interview), with the option of emigrating either this trip or in the future.
What type of visas should we apply for? If it's for a short to medium trip or for eventual emigration.
I understood that if my wife enters with a tourist visa and we then apply from within the US to emigrate it is frowned upon and can be denied.
Is this something we would definitely need a lawyer for? What would the costs be?
