Residency & Status Updates
What is adjustment of status?
Adjustment of status is the process that allows an eligible foreign national to apply for Lawful Permanent Resident status (a Green Card) while physically remaining inside the United States. There is no need to travel back to their home country for an overseas embassy interview.
What is a Lawful Permanent Resident (LPR)?
A Lawful Permanent Resident, commonly known as a Green Card holder, is a non-citizen who has been officially granted the authorization to live and work permanently in the United States. LPRs enjoy most of the rights of U.S. citizens, however, they cannot vote in federal elections and can lose their status if they commit certain crimes or abandon their residence.
What is naturalization?
Naturalization is the formal legal process through which a qualified foreign national voluntarily becomes a naturalized U.S. citizen. To qualify, applicants must typically hold a Green Card for a specific period, demonstrate good moral character, pass an English and civics test, and take an Oath of Allegiance.
What is consular processing?
Consular processing is the method used by individuals outside the U.S. to obtain an immigrant visa through a U.S. Department of State embassy or consulate in their home country. Once the visa is approved and the applicant enters the U.S., they officially become a Lawful Permanent Resident.
What is unlawful presence?
Unlawful presence refers to any period of time a person spends in the United States after their authorized stay has expired or after entering the country without official inspection. Accumulating unlawful presence can trigger severe long-term re-entry bans that prevent a person from legally returning to the U.S. for years.
Protection & Relief Programs
What is political asylum?
Political asylum is a form of humanitarian protection granted to individuals already in the U.S. who cannot return home due to a well-founded fear of persecution. The persecution must be based on specific grounds, including race, religion, nationality, political opinion, or membership in a particular social group.
What is Temporary Protected Status (TPS)?
Temporary Protected Status is a temporary humanitarian benefit granted by the U.S. government to eligible nationals of designated countries unsafe to return to due to armed conflict, environmental disasters, or extraordinary conditions. TPS provides recipients with temporary protection from deportation and eligibility for a U.S. work permit.
What is DACA?
Deferred Action for Childhood Arrivals (DACA) is an administrative policy that protects eligible undocumented individuals brought to the U.S. as children from deportation. Recipients receive temporary protection and renewable work authorization, though DACA does not provide a direct pathway to permanent residency or citizenship.
What is a U Visa?
A U Visa is a temporary non-immigrant status designated for victims of certain qualifying crimes who have suffered mental or physical abuse in the U.S. It provides temporary legal status and work authorization to encourage victims to assist law enforcement agencies in investigating or prosecuting criminal activity.
What is VAWA cancellation of removal?
VAWA cancellation of removal is a form of relief allowing non-citizens who have been abused by a U.S. citizen or LPR spouse or parent to request a dismissal of deportation proceedings. Successful applicants are granted Lawful Permanent Residency, allowing them to gain legal status independently of their abuser.

Enforcement & Legal Proceedings
What is expedited removal?
Expedited removal is a summary deportation process that allows U.S. border enforcement officers to swiftly deport certain non-citizens without a formal hearing before an immigration judge. It primarily applies to individuals who arrive at a port of entry or cross the border without valid travel documentation or with fraudulent papers.
What is voluntary departure?
Voluntary departure is an agreement allowing a non-citizen to leave the United States at their own expense within a specified timeframe instead of being formally deported. Choosing voluntary departure prevents a formal order of deportation from appearing on the individual’s record, avoiding the strict mandatory re-entry bans associated with removal.
What is a Notice to Appear (NTA)?
A Notice to Appear is the official charging document issued by the Department of Homeland Security that formally initiates removal proceedings against a non-citizen. It outlines the legal reasons the government believes the person is removable and directs them to appear before an immigration judge.
What is an immigration detainer?
An immigration detainer is a request issued by Immigration and Customs Enforcement (ICE) to local, state, or federal law enforcement agencies asking them to maintain custody of an individual for up to 48 hours beyond their scheduled release. This extra time allows ICE officers to take custody of the individual for potential deportation proceedings.
What is a Master Calendar Hearing?
A Master Calendar Hearing is the initial, procedural court date in an immigration court removal case. During this brief session, the judge handles preliminary administrative matters, establishes formal pleadings, and schedules deadlines or future individual trial dates.
Employment & Sponsorship
What is PERM labor certification?
PERM labor certification is the initial step in most employment-based Green Card applications, overseen by the U.S. Department of Labor. It requires a U.S. employer to prove that there are no qualified, able, and willing U.S. workers available to fill the job opening and that hiring a foreign worker will not adversely affect domestic wages.
What is an Employment Authorization Document (EAD)?
An Employment Authorization Document, commonly known as a work permit, is an official card issued by USCIS that grants non-citizens temporary legal permission to work in the United States. It is typically issued to individuals with pending Green Card applications, asylum applicants, TPS holders, and DACA recipients.
What is an Affidavit of Support (Form I-864)?
An Affidavit of Support is a legally binding contract between a financial sponsor and the U.S. government ensuring that an intending immigrant will have adequate financial backing. By signing it, the sponsor agrees to maintain the immigrant above specified income thresholds so they do not rely on public assistance.
What is a public charge?
Public charge is a ground of inadmissibility evaluated by immigration authorities to determine if an applicant is likely to become primarily dependent on government financial aid. If an individual is determined to be a public charge, their application for a visa or Green Card can be denied.
What is an H-1B visa cap?
The H-1B visa cap is the statutory annual limit set by Congress on the maximum number of new H-1B specialty occupation visas issued to foreign workers per fiscal year. Because demand from employers consistently exceeds the statutory limit, USCIS conducts an annual computer-generated lottery to select applicants.
