I am on H1-b visa , I am right now 30 hrs/week (part time). Now my company is filing amendment for 40 hrs/week (full time). usually takes 4-6 months(as I heard). I never been out of USA since my H1b approval and visa is expired (never did go for stamping). My wife came here on F2 visa and then we changed it to H4 (as soon as I got my H1b approved). She has never been to out of country either. Now she has to go to India for couple of weeks to months . Is it advisable to go for visa stamp in India with out me having visa stamp for H1b ( my status is still valid but visa is expired)? or also before approval of 40hrs/week ?
