Chain Migration refers to the endless chains of foreign nationals who are allowed to immigrate to the United States because citizens and lawful permanent residents are allowed to sponsor their non-nuclear family members.
HOW CHAIN MIGRATION WORKS
Chain Migration starts with a foreign citizen chosen by our government to be admitted on the basis of what he/she is supposed to offer in our national interest. The Original Immigrant is allowed to bring in his/her nuclear family consisting of a spouse and minor children. After that, the chain begins. Once the Original Immigrant and his/her spouse becomes a U.S. citizen, they can petition for their parents, adult sons/daughters and their spouses and children, and their adult siblings.
The Family-Chain categories are divided into four separate preferences:
- 1st Preference: Unmarried sons/daughters of U.S. citizens and their children (capped at 23,400/year)
- 2nd Preference: Spouses, children, and unmarried sons/daughters of green card holders (capped at 114,000/year)
- 3rd Preference: Married sons/daughters of U.S. citizens and their spouses and children (capped at 23,400/year)
- 4th Preference: Brothers/sisters of U.S. citizens (at least 21 years of age) and their spouses and children (capped at (65,000/year.
