Dear,
I have completed my Master in USA and applied for my H1B,
H1b got approved but my COS(F1 to H1) got rejected.
So, to get COS done I have travelled to home country. For some personal reasons I have withdrawn my H1b and travelled back to US on H4.
1) Now, If I want to change back visa my status to H1b do I have to file new H1b or can I go for COS ?
2) If only COS, Can I apply it immediately or should I wait for some period of time on H4?
Thanks,
Sai
