The White House wants to re-open travel, which would boost business for the airlines and tourism industry, but is not ready to immediately lift restrictions because of the rising COVID-19 case load and highly transmissible COVID-19 Delta variant, the official said.
The official's comments were the strongest signal to date that the White House sees a path to unwinding those restrictions. The White House has held discussions with airlines and others about how it would implement a policy of requiring vaccines for foreign visitors. The administration must also answer other questions including what proof it would accept of vaccination and if the United States would accept vaccines that some countries are using but which have not yet been authorized by US regulators.
Currently, the only foreign travelers allowed to cross by land into the United States from Mexico and Canada are essential workers such as truck drivers or nurses. Former President Donald Trump's administration did not set any metrics for adding or dropping countries from the list, and neither has Biden's. Trump did attempt to lift European countries from the restrictions in January but Biden reinstated the restrictions before they were dropped.
本來就應該是這樣的。
