My step-daughter's visa shows a 10 year expiration date. I think it should be two years.
Marriage date: 8/18/2020
I-130 Sent for wife and step-daughter: 9/14/2020
Wife approved and entered US: 8/11/2021 Visa expires: 8/11/2023
Step-daughter approved a few months later and entered US: 2/9/2022 Visa expires: 2/9/2032
She entered less than 2 years after the marriage, so from my understanding, her Visa should expire on 2/9/2024.
