My wife (US citizen) is filing I-130 to petition a green card for her brother. However, her brother doesn’t have a passport.
Question: Is a passport or travel document number required in the application?
If her brother gets a passport, it will expire in 10 years anyways (it takes more than 10 years for a priority date to become current). That just makes me wonder if it is really needed. The passport number will be different when he is ready to immigrate.
