The White House is considering the possibility that foreign visitors will be asked for vaccine evidence

The White House co-ordinator for COVID-19, Jeff Zients, told Reuters news agency that many federal agencies are considering the possibility.

The United States still does not have a deadline for the resumption of international travel, given the spread of the delta version of the Coronavirus, which causes COVID-19.

The United States originally imposed travel restrictions from China in January 2020. Since then, several other countries, including India and many countries in Europe, have faced similar restrictions.

Two issues facing this plan are what would be accepted as evidence of the vaccine and whether the United States would accept documentation from those who received vaccines that were not approved in the US.

Meanwhile, on the border with Mexico, where there are a record number of immigrants trying to cross the border, the test vaccine is not required before migrants are set free in the United States.

Washington Examiner, wrote that during the last week of July, about 7,000 immigrants were released in the border town of McAllen in Texas, out of which 1,500 came positive in testing for COVID-19.

Washington Post, wrote that President Joe Biden's administration is drafting plans to vaccinate immigrants.
