USA visiting visa documents required.

Hi Team,

I hold an Indian Passport. Currently I'm working in UK under Tier 2 Visa ICT for last 3 and half years.

I'm planning to visit USA to meet my sister and brother-in-law (who holds a green card in US).

Can you please let me know the answers to my queries:

1) USA Visiting Visa Documents Required ?
2) Am I eligible to apply USA visiting visa in UK country with Indian Passport?
3) Visa Processing Time?


Thanks,
Ajay
