JoeF and others,
How can a U.S. citizen sponsor a parent from within the U.S. if the parent entered the U.S. on a visa waiver (i.e. from a European country that does not require a visa for entering the U.S.)
Is there a way to that change status? In other words, how do you sponsor your parents from inside of the U.S. if they don't require a visa to come here?
The green visa waiver states on the back that one can not change to another type of visa while in the U.S.
Is consular processing the only option?
Please comment. Thanks
