H4 stamping still valid for reentry after H1 petition effective

[goodtoask]

Hi,

 

I entered on H4 before my H1 COS is effective. On Oct 1st H1 COS is effective and started working and now want to move back to H4. Planning to travel and come back on H4.

 

Can I reenter on current H4 visa stamp in my passport (expiry jul 2016) or do I need to go for H4 stamping again?

 

Appreciate your help.

You can use existing valid H4 visa and a copy of your spouse's I797.

Thank you.

One more question. Will there be any questions regarding my H1 and current employment at POE? Do I need to carry any documents related to H1 and employment? Please clarify. Appreciate your help.
