Immigration Law, Explained in Plain Language
Immigration law is one of the most complex areas of U.S. law — but you should not need a law degree to understand your own case. Here is a clear map of how it works, and where an attorney fits in.
The Main Areas of Immigration Law
Family-Based Immigration
The most common path to a green card. U.S. citizens and permanent residents petition for spouses, children, parents, and siblings.
Humanitarian Relief
Protections for people who have suffered abuse or hardship, including VAWA self-petitions and related forms of relief.
Business & Investment
Pathways tied to entrepreneurship and investment, such as the E-2 treaty investor visa for nationals of qualifying countries.
Citizenship & Naturalization
Becoming a U.S. citizen through the N-400 process — eligibility, the civics test, the interview, and the oath.
Removal Defense
Defending against deportation in immigration court, including bond, relief applications, and responses to a Notice to Appear.
How a Case Moves Through the System
01
Petition
A qualifying relative or the applicant files the petition that establishes eligibility (for example, Form I-130).
02
Wait for a visa
Depending on the category, there may be an immediate opening or a wait for a priority date to become current.
03
Apply for status
The applicant adjusts status in the U.S. (Form I-485) or processes through a consulate abroad.
04
Interview & decision
Most cases include an interview. When approved, the applicant receives their green card or benefit.
