” People I know who became US citizens had to turn over their other passports.”
****
bullsh*t
You mean a US citizen who is also a dual citizen of Canada is supposed to turn over the Canadian passport? Really...(eyes looking up)
Did you really just say that?? LOL
Other passports are not to be used when you become a US citizen.
It looks like use of other countries’ passports come down to whether those countries allow dual citizenship.
