"Why does the CR1 take longer for a green card sponsor?"
Immigrant visas for the family-sponsored immigrant preference categories are numerically limited, so they are not always immediately available.
Your family member’s preference category will determine how long he or she will have to wait for an immigrant visa number.
Second Preference (2A): Spouses of Green Card holders, unmarried children (under 21) of permanent residents.
If you are a prospective immigrant, you can find your priority date on Form I-797, Notice of Action, for the petition filed on your behalf. The waiting time before receiving an immigrant visa or adjusting status depends on:
- The demand for and supply of immigrant visas.
- The per-country visa limitations.
- The number of visas allocated for your preference category.
