President Donald Trump has dramatically restricted America's refugee intake since he took office, and though he has demanded that "extreme vetting" be implemented for refugees coming from majority-Muslim countries, those closest to the refugee-vetting process say the current system is already as extreme as it gets.
The refugees undergo years of screening filled with intensive interviews, detailed background checks from multiple government agencies, biometric data collection, medical tests, and constant scrutiny from the US officials who vet them.
