Can a non citizen buy a car in us?

Yes, a non-citizen can buy a car in the U.S. However, they typically need to provide identification, such as a passport or a driver's license from their home country, and may also need a taxpayer identification number (ITIN) or a Social Security number if they have one. Additionally, the process may vary by state, so it's important to check local regulations regarding vehicle purchases for non-residents.
