Thanks to community for helping out other people with doubts and questions.
I have both B1 and H4 visa.
Currently i am on business trip , so on B1 visa. my purpose of visit will be done in few weeks and i have return ticket.
I am planning to come back on H4 visa to stay with my spouse.
is it requried to exit country and come again to change the visa type in i94 ?
Is it possible to get it done from US itself ? (i can save money for flight for coming back)
how long does it take if i do this visa type change from here in US ?
Thanks a lot friends for taking out time to reply…
