The new travel ban on citizens of 12 countries that restricted access to people from seven others includes some exceptions, part of the administration’s efforts to withstand the legal challenges that a similar policy known as the “Muslim ban” faced during Donald Trump's first administration.

The addition of visa overstays as a rationale could provide an opening for new legal challenges, migrant advocates say.
