From the website of US Mission-Viet Nam:
Lapse in U.S. Government Appropriations
The Federal Government of the United States of America is currently in a Lapse of Appropriations period.
Scheduled passport and visas services, and emergency services for U.S. citizens, will continue at the U.S. Embassy Hanoi and our Consulate in Ho Chi Minh City during the lapse in appropriations as the situation permits.
The American Centers and EducationUSA advising offices in Hanoi and Ho Chi Minh City will be closed to the public during the lapse in appropriations. All schedule programs are also postponed until further notice.
We will not update this account until full operations resume, with the exception of urgent safety and security information.
EducationUSA is unable to work with international students who have an interest in study in the USA because DJT wants his border wall. The irony is so thick you can cut it with a knife.
Shalom (שלום), MAA
