Some U.S. states have travel restrictions because of the COVID-19 pandemic. If you must travel, United Airlines has created a handy map that shows which states have or do not have restrictions.
The map is color coded by the level of restriction. View the map.

For U.S. travel, check the Centers for Disease Control and Prevention (CDC) State & Territorial Health Department Websites directory. I browsed this directory tonight, and it takes some digging to find information on some of the states’ sites listed here.
For international travel, go to the U.S. Department of State’s COVID-19 Country Specific Information page.
