So far I know they gave a Yemeni, 3 month single entry. Something called rule of reciprocity, where the US treats you how your country treats them, Chinese and Indian nationals with RTD get 10 years multiple entry.
But the thing is, it's not fair, some didn't ask for their nationalities, and now are refugees, and have nothing to do with their nations or how they issue visas to Americans. I'm hoping some other national has had different experience, and gives us hope.
Visa system aren’t known for being fair. The US can admit who they want for how long they want. Even with Canadian citizenship you can be denied entry.
