Immigration law governs how non-citizens may enter, live, work, and become citizens in a country, and the conditions and consequences attached to their status. In the United States it is primarily federal law, and it affects individuals, families, employers, and communities.
This field covers a wide range of situations. It includes temporary visas for visitors, students, and workers; paths to permanent residence; family-based and employment-based processes; humanitarian protections for people fleeing harm; the requirements and process for becoming a citizen; and removal, the legal process by which a non-citizen may be ordered to leave. Immigration law also intersects with other areas — for example, criminal matters and family relationships can affect a person's immigration status.
For a non-lawyer, several concepts are important. Immigration status comes in many forms, each with its own rules, rights, and limits. Processes often involve detailed applications, supporting evidence, and strict deadlines, and decisions can have lasting consequences for a person and their family. The law in this area can change, and outcomes depend heavily on individual circumstances. People and employers commonly consult immigration lawyers when applying for a visa or residence, sponsoring a family member or employee, pursuing citizenship, seeking humanitarian protection, or facing removal proceedings, where the stakes are especially high.
