I am an Indian citizen working as Business Analyst with a reputed Software MNC. I am travelling to London on work permit for 6-8 months, by October end 2010. However, i wish to visit US on B2 visa in December just for one week to attend one of my close friend's housewarming party and to tour US with my friends staying there. My friend has sent me an invitation for the party, and is ready to sponsor me, if required.
Please suggest, will it be possible for me to apply for visa from London. I have no intentions to stay in US for more than a week. How much funds do i need to show in case i go for self- sponsorship. Please advise.
