Quick Overview

An in-depth guide to the federal immigration system, covering visa categories, green card applications, deportation defense, asylum claims, and the complex interplay between USCIS, immigration courts, and the Board of Immigration Appeals.

The Federal Immigration Legal Framework

Key Immigration Statutes and Agencies

Federal immigration law is primarily governed by the Immigration and Nationality Act (INA), codified at 8 U.S.C. § 1101 et seq. This comprehensive statute establishes the categories of immigrants and nonimmigrants, grounds for admission and exclusion, and procedures for removal (deportation) proceedings.

Three primary federal agencies administer immigration law: U.S. Citizenship and Immigration Services (USCIS), which handles applications for immigration benefits; Immigration and Customs Enforcement (ICE), which handles enforcement and removal; and Customs and Border Protection (CBP), which manages ports of entry and border security.

Immigration courts operate under the Executive Office for Immigration Review (EOIR), a component of the Department of Justice. Immigration judges conduct removal proceedings and decide whether individuals should be deported or granted relief from removal. Appeals from immigration court decisions go to the Board of Immigration Appeals (BIA).

Federal circuit courts of appeals have jurisdiction to review final orders of removal under 8 U.S.C. § 1252. The scope of judicial review varies depending on the type of claim, with constitutional claims and questions of law generally receiving de novo review, while factual findings are reviewed under the substantial evidence standard.

Common Immigration Relief Strategies

Paths to Legal Status and Deportation Defense

Asylum under INA § 208 provides protection for individuals who have suffered persecution or have a well-founded fear of persecution on account of race, religion, nationality, membership in a particular social group, or political opinion. Applicants must file within one year of arrival in the United States unless they qualify for an exception.

Cancellation of removal under INA § 240A is available to certain long-term permanent residents and non-permanent residents who can demonstrate continuous physical presence, good moral character, and that removal would result in exceptional and extremely unusual hardship to a qualifying U.S. citizen or permanent resident relative.

Adjustment of status under INA § 245 allows eligible individuals already in the United States to apply for permanent residence without leaving the country. This requires an approved immigrant visa petition, an available visa number, and admissibility to the United States.

Waivers of inadmissibility under INA § 212 may be available for individuals who are otherwise ineligible for admission due to prior immigration violations, criminal convictions, or other grounds. The I-601 waiver requires demonstrating extreme hardship to a qualifying relative.

Critical Mistakes in Immigration Cases

Errors That Can Derail Your Immigration Case

Missing filing deadlines, particularly the one-year asylum filing deadline, which can permanently bar eligibility for asylum relief.

Failing to disclose prior immigration violations, criminal history, or previous applications, which can result in findings of fraud or misrepresentation.

Not maintaining valid immigration status while applications are pending, which can affect eligibility for adjustment of status.

Traveling outside the United States without advance parole while an adjustment of status application is pending, which can result in abandonment of the application.

Failing to appear at immigration court hearings, which typically results in an in absentia removal order that can be difficult to reopen.
