Can I travel to India when my H1 is under process & come back in H4?

This is my secanrio,

My Husband is in H1 transfer and currently it ia under RFE. Both of previous our Visa(s) and i94 are expired and i am planning to apply for H1 in 2014.

The questions are,

  1. Can i travel to india after my husband’s H1 transfer status is aproved?

  2. If i file H1 and go to india can i come back H4 status?

  3. If i go to india will this affect my H1 process?

  4. Can i get H4 stamping(which i think easy to get) and come back to US and once my H1 is approved can i start working or Will I have to go for H1 stamping?

Please advice
