Immigration law is a complex legal field that governs the process of individuals entering, residing, and working in a country. It covers a range of issues, including visa applications, obtaining permanent residency (green cards), seeking citizenship through naturalization, and applying for asylum or refugee status. Immigration law also addresses family reunification, employment-based immigration, and defense against deportation or removal proceedings. Additionally, it plays a crucial role in protecting the rights of immigrants while ensuring that national security and immigration policies are upheld. Individuals and businesses often require expert legal guidance to navigate the intricate rules and procedures associated with immigration.
