Doubt any 'full' time... might do a photo op, to make it appear like he really cares. Just remember, 'we the people' by law, pay taxes to fund these migrants, for the length of their lives, right here in the USA to the tune of billions.
Another possibility is to support local Christian communities close to areas that generate refugees if possible. They may be more heroic confessors (and sometimes martyrs) than we might imagine. Holy Spirit under pressure = spiritual dynamite.
