"While COVID-19 is no longer the disruptive threat that it once was, the Administration opposes Congressional action to reverse the vaccination requirement for noncitizen nonimmigrants entering the United States by air," the statement said.
The US House of Representatives earlier on Tuesday advanced legislation that would terminate the proof-of-vaccination requirement, which was imposed at the height of the pandemic on the advice of the Centers for Disease Control and Prevention.
But the statement from the OMB suggests that Biden could veto the legislation in the event that it passes both chambers of Congress and gets sent to his desk.
It remains unclear whether the legislation will make it through the US Senate, in which Democrats currently hold the majority.
