I have applied for the H1B visa in 2012 June and the status is now the petition is approved. But I did not go for the stamping.
Now currently I am outside the USA and my spouse has the H1B and I have the H4 Visa stamped.
If I will travel to US using the H4 and If I wish , Can I change the H4 to H1B after enter in to US?
How much time is required to do H4 to H1 transfer? I am the first time H1 petitioner.
Should I go out of USA to do the transfer? After which stage I can start work in USA?
Thanks in advance…
