I personally did not get my wife to change her last name to mine due to two reasons:
- Possible issues with paper work during the process.
- My last name was translated from Ukrainian to English, as she is Russian the translation would be incorrect to have it done on her official documents upon marriage. We're waiting until she has status here before doing so, making sure the name is changed correctly.
It's not worth the hassle just for a name change. Wait until everything is finalized before proceeding with the change of a surname.
