How easy will it be for us to get her a visa for a seven day stay in new york? We are really eager to book the flights, but don't want to book them if she won't be able to get a visa.
She'd probably have to go to Warsaw to apply. It helps if you have someone write some sort of invitation stressing responsibility e.g. Insurance coverage, food, place to stay and $ for a flight back if necessary. It also helps a lot if she's a student or has equal "strong ties" to Poland....and most of ther time, there's not much of a wait.
Good luck!
