    Frequently Asked Questions About U.S. Green Cards

    Can I get a green card without living in the United States?

    Yes. If you live abroad, you can apply through a process called consular processing. This allows you to obtain a green card through a U.S. embassy or consulate in your home country. Our firm has international offices in Mexico, Portugal and Thailand to assist you directly in your region.

    Do I need a job offer to apply for a green card?

    In most employment-based green card categories, yes. You typically need a U.S. employer to sponsor you and complete a labor certification (PERM). However, certain categories such as EB-1A (Extraordinary Ability) and EB-2 NIW (National Interest Waiver) allow qualified individuals to self-petition without employer sponsorship.

    How long does it take to get a green card through marriage?

    The timeline depends on whether your spouse is applying from within the U.S. or through a consulate abroad. Most marriage-based green card cases take about 18 months from start to finish, although processing times can vary.

    Can I apply for a green card from Washington, D.C.?

    Yes. If you are living in the United States, including Washington, D.C., Maryland, or Virginia, you may be eligible to apply through adjustment of status. Our Washington, D.C.-based immigration attorneys handle all aspects of the application and interview process locally.

    Which employment-based green card category is right for me?

    That depends on your education, work history, and immigration goals. We work with professionals and executives to determine eligibility for EB-1, EB-2, or EB-3 green cards and guide you through labor certification, documentation, and long-term strategy.
