Can a U.S. citizen sponsor a half-sister or half-brother for a green card?
Half-blood relationships qualify as siblings for U.S. immigration purposes.
I was born in the U.S., after which my father divorced my mother and returned to the Philippines. He remarried, and they had children, so I now have half-siblings. My father would love for them to have the possibility of U.S. citizenship as well, and has contacted me about this. Is it possible for me to sponsor my half-brothers and half-sisters for U.S. immigration even though we don’t share the same mother?
