Wenera,
I asked about the address since I was not sure about it. The address the embassy provided did not have attention to whom it may concern. It sounds that that address(Washington D.C) for the people walking in only. Imagine, the bank has a lot of mails each day.
If there is no attention to whom, who is going to accept the letter. Also, I called to figure out to the bank. It turned out that the customer service gave a total different address. I don't know the virginia adress that has attention will go to Sri Lanka embassy or to other organization. I surely would like to have it send to Sri Lanka Embassy. What do you think?
I am cooperating with all students and Thai community here in my city. Most people of Thai community in my city are doctors (>30 doctors or professors), professors teaching at Washington University. Some of them volunteer for the program of helping people without border. I need to have correct information. Thank you.
