Re: actually
AC: "if I was applying for a visa I would hope that the Americans could not see that"
The Russian embassy in London is located on a corner and if you want to visit and get a visa you can queue up.* This was so that the UK's (and presumably USA's) intelligence agencies could see exactly who was applying for a visa:
"The Embassy of Russia in London is the diplomatic mission of Russia in the United Kingdom. The main building and Consular section is located at 5 and 6-7 Kensington Palace Gardens at the junction with Bayswater Road;" (https://en.wikipedia.org/wiki/Embassy_of_Russia,_London)
*Probably best to wait a bit at the moment
