What Clients Say

Client

H-1B → Green Card · Cambridge, MA
★★★★★
"My employer used Fragomen for my H-1B and then my green card process. Every deadline was met, every document was perfect. When USCIS issued an RFE on my I-140, the team had a response filed within two weeks. I now have my green card."
Client
Priya R.
O-1 Visa · Boston Biotech
★★★★★
"Getting an O-1 as a researcher is complicated. Fragomen's team knew exactly how to document my publications and citations to meet the extraordinary ability standard. Approved first try. They made a stressful process manageable."
Client
HR Director, Boston Tech Company
Corporate Immigration Program

"We run a global tech team and Fragomen manages our entire US immigration program — 30+ active cases at any time. Their tracking system, their compliance team, and their legal knowledge have been essential as immigration rules keep shifting."

FAQ

Common Immigration Questions

What's the difference between an H-1B and an O-1 visa?
An H-1B requires a sponsoring employer and is for specialty occupation workers (bachelor's degree or higher required). It has an annual lottery cap of 85,000 visas. An O-1 is for individuals with extraordinary ability in their field — artists, researchers, entrepreneurs — and has no annual cap. Fragomen helps determine which classification best fits your background.
How long does a green card take through an employer?
Employment-based green card timelines vary enormously based on your country of birth and category. EB-1 and EB-2 NIW for those born in countries other than India or China can be 1 to 3 years. Indian-born applicants in EB-3 face backlogs of decades. An immigration attorney can map out your realistic timeline.
Can Fragomen help with university and research institution immigration?
Yes. Many of Boston's universities and research hospitals use Fragomen for faculty, postdoctoral researchers, and visiting scholars. The firm is experienced with J-1, H-1B, TN, O-1, and EB-1A/EB-2 NIW petitions common in academic settings.
Does Fragomen handle individual (non-corporate) immigration?
Yes. The Boston office offers concierge immigration services for individuals and families — including family-based green cards, citizenship applications, DACA renewals, asylum, and removal defense. Contact the office to discuss whether your situation is within their current practice scope.
What should I do if my visa status has lapsed?
Contact an immigration attorney immediately — do not wait. Unlawful presence accrues quickly and can trigger bars on re-entry of 3 or 10 years. An attorney can assess your situation, identify any applicable exceptions, and help you find the best path forward.
