Wasn't one of the issues with the visa policy/travel band the lack of ability to verify identities due to some of the country's passport and identification offices having been taken over by insurgents? IIRC even the head of the CIA mentioned there was no way to vet the backgrounds of folks attempting entry from certain countries and Obama had also signed a law effecting entrance by the people identified in Trumps temporary order. The people you care about are no doubt good people and deserving of entry and citizenship and I understand your angst about them being affected but controlling immigration to the United States is important. The ban was needed until a way to properly identify people was in place especially from counties previously acknowledged as supporting terrorism.
