H1b stamping from Uk


I am an indian employee of company X and i have an approved H1B petition sponsored by company X (not yet stamped but i have the petition number).Presently i am in the UK on a project from company X . I got a job in company Y based in USA .I assume company Y will have to apply for a new visa under cap exemmpt catagory (correct me if i am wrong ). My question- can i go for the visa interview in the USA embassy in UK or i should go for the interview in India?


You need to talk to someone at UK embassy. few embassies do not encourage such things and wants you to go to home country. So, call the UK consulate and then schedule the interview
