thank you so much for your important information.

I still have some specific question.

1. How long did it take to get your permit?
2. when you submit your application to new york embassy, you should have submit your passport. so how can you apply a US visa to go there.
3. What is the purpose of your interview? what did they ask you?
4. is there any important thing I should be very careful to obtain the permit successfully.

Could you help me again?

thanks.
