The only thing they want to know is that he won't be staying in the US and will leave. There's no definite list of things to bring, he'll just need to show he has ties to the UK. I'm going in February and am taking my mortgage details and getting my work to write a letter stating when I'm coming back (just because it's not the first time I've been and am a worrier and want to make totally sure
) I'll also have my return ticket.
The questioning again is not set in stone but will probably be roughly:
- Are you visiting for business or pleasure?
- Do you have friends or family in the US?
- How do you know them?
- that'll probably be it.
All you need to do is answer the question honestly and don't volenteer any information unless asked. Also do not expect the miserable b*stards to smile at all.
