*H1B extension through CompanyA approved until Nov 2011
*wife received her visa stamp in 2009 valid until Nov '11. I didnt leave US then.
*But this year my H1B stamping was denied at consulate in home country.
*CompanyB filed for my H1B transfer through consular processing and got an I797 approval notice valid until April 1st 2012 (time recapture).
I got my new H1B visa stamped by the consulate and with validity till April 2012. My wife did not accompany me for stamping. We both plan to re-enter the US together in Dec 2010.

Question:
Does my wife need to get her visa stamped again even though her current visa (through companyA) is valid until Nov 2011? Also when my new I797 was approved no separate document was issued for my wife. So what documents will we have to carry at POE?
