From employment-based green cards to family reunification and asylum — Astrea handles the full spectrum of immigration cases.
Employment-based green cards (EB-1 through EB-5) grant US permanent residency through an applicant's extraordinary achievements, advanced degree, or qualifying investment. Each category has distinct USCIS criteria filed on Form I-140, with concurrent I-485 filing available when a visa number is current.
Non-immigrant work and investor visas authorize foreign nationals to live and work in the US for a defined period, with clear pathways to permanent residency. From specialty occupation workers and extraordinary ability performers to treaty investors, religious workers, students, and exchange visitors.
Family-based and humanitarian immigration provides a path to US residency for qualifying relatives of citizens or permanent residents, and for individuals facing persecution abroad. These cases coordinate multiple USCIS forms across agencies, consular posts, and immigration courts.
The EB-2 National Interest Waiver (NIW) is an employment-based green card for professionals with an advanced degree or exceptional ability whose work substantially benefits the United States. Unlike other EB-2 cases, NIW applicants self-petition via Form I-140 — no employer sponsorship or PERM labor certification is required. USCIS evaluates eligibility using the three-prong Dhruva test: substantial merit, well-positioned to advance the endeavor, and national benefit from waiving the job offer requirement. See USCIS EB-2 guidance.
Standard Form I-140 processing currently takes 6 to 24 months depending on the service center and visa category. Premium processing via Form I-907 reduces the adjudication window to 45 business days for most EB categories. As of 2026 the premium processing fee is $2,965. Current wait times are published monthly on the USCIS processing times page.
The O-1A visa is for individuals with extraordinary ability in sciences, education, business, or athletics — requiring evidence of sustained national or international acclaim across at least 3 of 10 USCIS criteria. The O-1B visa applies to extraordinary achievement in the arts, motion picture, or television industry. Both are nonimmigrant visas filed on Form I-129 and require a US-based petitioner or authorized agent. See USCIS O-1 guidance.
Adjustment of Status is filed on Form I-485 and allows an eligible person already inside the United States to apply for a green card without leaving the country. It is typically filed concurrently with Form I-131 (travel document), Form I-765 (employment authorization), and Form I-864 (Affidavit of Support), along with an approved immigrant petition such as an I-140. Eligible applicants may also work and travel while the I-485 is pending.
The L-1 visa allows US multinational companies to transfer managers and executives (L-1A) or specialized knowledge employees (L-1B) from a foreign affiliate, subsidiary, or parent company to a US office. The employee must have worked for the qualifying organization abroad for at least one continuous year within the past three years. L-1A holders can later self-petition for an EB-1C immigrant visa. See USCIS L-1A guidance.
Affirmative asylum allows a person not in removal proceedings to apply for US protection by filing Form I-589 with USCIS within one year of arriving in the United States. The applicant must demonstrate a well-founded fear of persecution based on race, religion, nationality, political opinion, or membership in a particular social group. A USCIS Asylum Office interview is scheduled after filing. There is no government filing fee for the I-589 itself.
Concurrent filing of I-140 and I-485 is allowed when a visa number is immediately available in the monthly Visa Bulletin for your preference category and country of birth. This strategy eliminates the waiting period between I-140 approval and the green card application, and is commonly used by EB-1 and EB-2 NIW applicants from countries with current priority dates. Concurrent filers also receive interim work and travel authorization while the I-485 is pending.
