The Texas Department of Motor Vehicles says new Texas residents have 30 days after moving to register a vehicle.
Its new-resident instructions say to take proof of insurance and proof of ownership, such as an out-of-state registration or title, to a county tax office. The first registration must be done in person.

Guadalupe County residents can make their first Texas registration at the county tax offices in Seguin or Schertz, both open 8 a.m. to 4:30 p.m. Monday through Friday except holidays. The county requires valid photo ID for every vehicle registration transaction. Bring it along with the vehicle documents before joining the line.
What to bring
TxDMV says a first-time registrant must complete Application for Texas Title and/or Registration, Form 130-U. Bring an insurance card and proof that you own the vehicle; the agency gives an out-of-state registration or title as examples of ownership proof. Guadalupe County separately requires a valid photo ID. These are the documents identified on the state and county pages, so check the state instructions and the county office page before your visit.
