I will be appearing for my H4 visa interview soon. My husband has had a H1-B transfer when he moved to a new job. His passport however still has the old stamp referring to his previous employer and the dates as applicable to the old H1-B.

Would my husband have to get his visa stamp renewed before I appear for the interview?

Note that I have all the documents from his new job i.e I 797, the I-129, employment verification, paystubs, W2.

Also, My husband had asked the immigration team and they said he did not have to get it restamped.

But I am a bit skeptical whether someone at the embassy might say something, like why does the passport not have the new stamp?

Please advise
