Hi,
I am in Wuhan China on F visa. I would like to bring my wife next week here.She is from Hyderabad, Andhra Pradesh.

1. Covering letter from applicant’s company or office?

2.Invitation letter from your relatives.What should be the contents of this invitation letter?
3. After she comes here we go to Singapore(actually my work place is Singapore). In this case, does she need return ticket to get VISA?
4. Does she need to produce bank statement? If yes, can I provide my account's statement?

I appreciate the reply.

Thanks
Sunil
