The process initiates with the US citizen spouse submitting a Form I-130 visa petition on behalf of their partner. If the spouse entered the US lawfully, they can concurrently apply for Adjustment of Status (Form I-485) and secure a green card without departing the US.

If the marriage transpired less than two years prior to the green card’s issuance, it will be valid for two years. Within the 90-day period preceding the green card’s expiration, the couple must submit a joint Form I-751 petition. This step ensures that the foreign-born spouse can obtain a ten-year green card, ensuring long-term residency.
