Family-Based Immigration

Achieve The American Dream With Our Family Immigration Services
At American Immigration Law Firm LLP, we understand how meaningful the American dream can be for you and your loved ones. Based in Monterey Park and serving clients across the Los Angeles area, our team is dedicated to helping families reunite in the United States. Attorneys Mariano F. Herrera from El Salvador and Juliette Potter from the Caribbean are immigrants themselves. They bring both personal insight and professional experience to ensure your immigration process is as smooth, compassionate and affordable as possible.
Understanding Family-Based Immigration Petitions

Other family members eligible to apply for a Green Card are described in the following family “preference immigrant” categories:

  • First preference (F1) – unmarried sons and daughters (21 years of age and older) of U.S. citizens;
  • Second preference (F2A) – spouses and children (unmarried and under 21 years of age) of lawful permanent residents;
  • Second preference (F2B) – unmarried sons and daughters (21 years of age and older) of lawful permanent residents;
  • Third preference (F3) – married sons and daughters of U.S. citizens; and
  • Fourth preference (F4) – brothers and sisters of U.S. citizens (if the U.S. citizen is 21 years of age and older).
  Having an experienced immigration attorney on your side can make a major difference. We help you complete the necessary paperwork, collect supporting documents and represent you throughout your immigration process. Our mission is to reunite you with your loved ones as quickly and seamlessly as possible.
Can I Bring My Family On A Nonimmigrant Visa?
Yes, in many cases you can. Some nonimmigrant visas allow your family to accompany you to the United States. For instance, if you hold an H-1B visa, your spouse and unmarried children under 21 can apply for H-4 dependent visas. Because every visa type has specific eligibility rules, it’s important to speak with a knowledgeable immigration lawyer to understand the best options for your situation.
How Long Does The Family Immigration Process Take?
The timeline for family-based immigration can vary significantly — from a few months to several years — depending on the visa category and your individual case. Reuniting family members can be a complex, emotional journey, but our attorneys work tirelessly to make it as efficient, stress-free and straightforward as possible. We are committed to helping families stay together in the United States.
Immigration Lawyers Who Understand The Process
Both Mariano F. Herrera and Juliette Potter have personally experienced the U.S. immigration process. They know how challenging and overwhelming it can feel. After meeting in law school in Florida and building their own lives together, they are now living their own version of the American dream — and they take pride in helping other immigrants achieve the same. Our firm assists U.S. citizens and their foreign family members with visa applications, extensions, adjustment of status (green cards) and naturalization to become U.S. citizens.
