Amending H1-B that has not started yet.

[sudhini]

I have my H1-B extension approved, which begins end of May. I got my extension approved through client XXX in mid March and moved to client YYY in end of March. Can I file my amendment on my H1-B extension before my extension start date.

I need to file and Amendment and go to stamping ASAP.


Thanks in advance.
