You might not have to go to Greensboro to get it. These people who seem to have plenty of resources to fly all over the world (I wonder if any of them have EBT cards)will bring it to you and save you the trouble of looking for it.
I know that Immigrationn Canada -- at least some of the time -- refuses entry to Americans listed as receiving SNAP or TANF benefits, on the basis that they may not be able to pay their expenses while in the country. This creates problems for guardians, foster parents, etc., who have the card but who are not in financial straits.
