Where will you go? go to Visa office or the Embassy?
Embassy is far away from visa office.

1) To go to visa office, better use metro, take Subway
to Friendship Heights and then take any metro buses
drive to south  of the Wisconsin Ave. The southbound
bus stop is right at the opposite of the exit of your
metro station. You won't miss it. If you drive, you
might have to pay for the parking. There're parking
lots at the opposite of the bussiness bureau of
embassy. When you see the business bureau (a big white
house, on your left hand), park your car or get out of
the bus, walk back about 100 meters is the Visa
office.

2) As to Embassy, you might have to call them to make
an appointment before you go.
