Travel while H4 to H1B transfer is in process

[USAResident]

Hi,

I am on H4 in USA and my H4 to H1B status transfer is in process.

My H4 Visa is valid until May 2013.

Can I travel to Canada and come back to US on H4 visa after my H1B is approved?

Please let me know ASAP.

Thank You

I guess then you have to go for H1 visa stamping in Canada, because if you enter us on H4, you will get a new I94 on H4 visa not on H1.

You H1 approval will have a new I94 with H1 status.
