To advise on immigration matters and represent clients in court

Immigration attorneys specialize in the complex field of immigration law, providing expert guidance to individuals and businesses navigating visa applications, green card processes, citizenship, and deportation defense. They represent clients before immigration courts and government agencies, ensuring legal compliance and advocating for their clients' rights throughout the often intricate and challenging immigration system.

4. Which family preference category covers brothers and sisters of adult U.S. citizens?
F4 - Fourth Preference

F4 (Fourth Preference) covers siblings of adult (21 or older) U.S. citizens and their spouses and children, and often has the longest backlogs of all family preference categories.

5. How should ethical dilemmas be handled in Visa Categories?
Follow established ethical guidelines, consult with supervisors, and prioritize stakeholder welfare

Ethical decision-making requires following professional guidelines and prioritizing the welfare of all stakeholders.

6. A beneficiary's priority date is current but the I-485 was filed with an incorrect fee. USCIS rejected the filing. What is the risk?
The priority date is lost if the visa bulletin retrogresses before the corrected filing is accepted

A rejected I-485 is treated as if never filed, so if the priority date retrogresses before resubmission, the applicant loses their window of eligibility.
