I AM ON B1/B2 VISA IN INDIA 10 YRS MULTIPLE,RECENTLY I HAVE APPLIED FOR H1B VISA AND HAS BEEN APPROVED FOR YEAR 2009,AND IS VALID FROM OCT 1 2008, I NEED A SUGGESTION CAN I TRAVEL
TO U.S.A ON MY B1/B2 VISA IN THIS MONTH END AND CHANGE STATUS TO H1B AND START WORKING FOR MY EMPLOYER,KINDLY PLEASE SUGGEST ME.

U cannot shift from B1 to H1 because when you enter United States, you get something called I-94. After that I-94 expires, you cannot stay in US though your B1Visa is valid or you have Valid H1b papers. So what you got to do is leave United states and get your H1 visa stamped then come back to United States. Then you get a fresh I-94

If your h1 is filled as change of status you cannot travel to India on B1 and come back but if it is filed as consular process then you can travel but you cannot start working on H1 B untill you get it stamped from any US consulate
