My L1B Visa got expired on 30-Dec-2011 and extension got approved Jun-27-2012. Am planning to go back to india and i know i have to go US embassy for Visa Stamping. Question here is there any possibilities to get rejection in Personal Appearance. Will US Consulate treat this extended petition same like fresh petition and may reject?. Please advise what would be advantage of having visa extension done in USA and will give some hope to get the stamping without any issues in India.
