I have a few questions:

1) If your application is approved, how flexible are they in scheduling an in-person interview?

2) If you don't live near one of the major airports, can you wait until your next flight connecting through one of these airports, say in the next 1-2 months?

3) How long is the interview? If you only have 2 hours connection time at one of these airports, is that enough time? Do you have to exit security, have the interview and then re-enter security to connect to your flight at most airports?

4) Are the interview locations next to the international terminals?

5) Are the interviews only held M-F 9-5 or are they available evenings and weekends as well?

Thanks.
