Based on recent experiences, how many days does it take to receive our passport back from Travisa for a 5 yr visa if sent by mail. I have bought air tickets in February 2011. I am supposed to fly to Chennai on 06/10/2011. I got an invitation from USCIS for a oath ceremony on 5/14. I am expecting my US passport by 5/16. My question is can I get Renuniciation certificate and Visa by 06/09/2011?
