Germany issued a travel advisory for the U.S., citing the risk of closed museums and national parks as the federal government partially shuts down in a budget impasse.

The update, posted on the German Foreign Ministry’s website today, said waiting times at U.S. immigration posts may be longer. Travelers to the U.S. “must expect U.S. national parks, national museums and public facilities to be closed until further notice,” according to the advisory.

The U.K. government, in a separate notice, said travelers may experience delays in air travel and at immigration.

U.K. citizens made up 6.1 percent of foreign visitors to the U.S. last year, the biggest share from Europe, followed by Germans at 2.9 percent, according to the Commerce Department.
