US-Alien

Registered Users (C)
1) what are the documents required for COS from h1 to h4.
2) are any pay stubs/W-2 required to be shown as proof of valid status existence during h1 period.
3) would a gap in employment during h1 have any consequences in the COS process to h4
4) can this change to h4 be done by getting a stamping at an embassy instead of COS in the US. If so, will Q2 be in effect again.
