The new Green Card rule announced by the US Citizenship and Immigration Services has led to major confusion and anxiety among Green Card applicants, as the new rule says one may not be allowed to stay in the US before they receive their permanent residence. They have to go back to their own country and file the application from a consulate there. The USCIS said people who come to the US temporarily have so far been allowed to change their status in the US which should not be the case as their intention does not match: they come temporarily but want to become permanent residents. Hence, they should go back to their country and follow the due process from there, with the intention of becoming a permanent citizen.
Experts said this is not a change of law but the minor tweak can have a huge impact. Earlier, the Donald Trump administration imposed a travel ban, visa ban on several countries but unlike the previous immigration bans, this can affect any country. But the most-affected countries are those that get the maximum Green Cards.
