Short trip

Often enough they go back to home country and then re-apply to get back. Once they have the degree they seem to be indispensable and are granted or they know someone that will sponsor them, like a "business person", etc..

The idea was to provide cultural exchange and return a better person "their" society. -----Willy happy
