Visa in old passeport which has not expired

[immihelp]

I am a French citizen who holds a French passport which expires in 2011.
I have now applied for a new biometric passport at the French consulate.
Meanwhile, my husband got an offer in US and I have been stamped H4 in my old passport. I am yet to receive my new passport. I assume that both passport numbers will not be the same. Do let me know if I get my
new passport and have a visa in my old passport, will I have problems to
enter the US? Or do I need to apply for a fresh visa with my new passport.

You just carry both the passport while entering the US. You will not have any problem
