Is US visitor's visa stamping possible from UK for Indian citizens on visit to UK?

Question

My parents are citizens of India with Indian passports and, are visiting my brother in UK for a couple of months on a visitors visa. I was interested in them joining me in US but couldn't have their US visa stamped from India because of some reason, before their travel from India to UK. They are now in UK. Does anyone have any idea if they could have their US visitor's visa stamped from UK & visit me in US here directly from UK ? I am on work visa (H1B) in US

Answer 1

no, usually the law says that you must apply from your own country and not as a tourist in another country, in order to get a visa.
