Visiting an Embassy / What are Embassies For?
Based on my experience many years living overseas, consulates and embassies of the USA are very unhelpful and generally not friendly. This goes for everything from supporting businesses/trade to adding pages to a passport. My friends from other countries have better stories about their embassies and some countries even hold parties for their citizens in country on certain big holidays.
My Indonesian customer lamented that he was always contacted by various EU embassies to attend trade promotion trips and they always helped to encourage him when he was doing business in those countries. From the USA he gets to attend a surly visa interview every couple of years and receives nothing else despite doing 100s of millions in trade with the country. His theory is we spend too much on weapons and have nothing left to promote trade.
