yes, you got it right there,
singh is not a family name, its given name, lots of people have it, there are chances of similar names, people face problems, while getting credit cards, bank loans, crossing US border, who have singh as a surname.
just because there is someone with the same name, and has done something wrong, like, murder, fraud, drug, etc etc.
it means more screening.
sit and wait, do nothing. there is nothing you can do.
good thing, medical extend,
anyone, who's waiting, Let me tell you one thing, patience is the only thing
there's nothing you can do,
they are working at their own pace
your files are in lonnnnnnggggggg line and waiting for their turns.
hope it makes thing clear, good luck
