Russians Engaged in Threating Ukraine Refuge Now Act or the RETURN Act This bill prohibits the U.S. government from charging U.S. citizens or lawful permanent residents for their evacuation related to Russia's invasion of Ukraine. Specifically, the Department of State must waive repayment for travel expenses incurred on behalf of such an individual as part of the evacuation from Ukraine. Similarly, no federal employee may solicit or accept funds from such an individual as a condition of using government-provided transportation to repatriate the individual to the United States. No traveler may be denied State Department-sponsored air travel related to such an evacuation due to a failure to provide proof of a negative COVID-19 test or recovery from COVID-19.
