Is there an organization that I can donate cash to that gives direct cash assistance to refugees?

I see women with infants panhandling in sub zero temps and I want to give them money but that incentivizes sitting out in freezing weather, so I usually don’t. But I know that direct cash can be so helpful to cover expenses that food pantries and clothes donations don’t. Is there a reputable organization I can donate to that will support people by giving them money or is that like illegal?
