Hello everyone,
my sister is in a unique situation. She’s a native born U.S. citizen but spent most of her life in UAE and married my brother in law in Pakistan and has been living in Saudi Arabia since 2015 till now. She wants to immigrate back to US now with my niece (also a native born U.S. citizen) along with my brother in law. However we aren’t sure about how to start the process for spousal visa and where should it start since he’s a Pakistani citizen currently living in Saudi Arabia. I live in US and know I would need to sponsor her family which isn’t an issue but not sure how to start this process. Thank you.
