WASHINGTON — The Trump administration is considering suspending or limiting U.S. entry for individuals from countries with high rates of short-term visa overstays. That’s according to a memo signed Monday by President Donald Trump that directs his administration to examine ways to minimize overstays as part of a larger focus on immigration. The memo directs the secretaries of state and homeland security to find effective ways to combat what the administration says is a rampant number of overstays.
