Testimonials
I felt lost starting the O-1A process. Within two days I had three vetted lawyers to choose from and a clear evidence checklist. We've just begun pulling documents, and for the first time it feels not overwhelming. The fast turnaround gave me confidence to actually move forward instead of procrastinating.
RahulO-1A
I was debating between NIW and O-1A, and every attorney I spoke with gave a different answer. Through this service, I got a shortlist with transparent fees and timelines the next day. I haven't filed yet, but I already know which attorney I'll retain and exactly what gaps I need to close. That clarity saved me weeks of uncertainty.
AlexEB-2 NIW
Big news – my O-1A petition was just approved! 🎉 Anna, the attorney I connected with through the platform, was fast, clear, and incredibly founder-friendly. From the initial playbook to the final submission, everything felt smooth and professional. What could have been months of wasted time turned into a confident, successful application.

FAQ
Are you a law firm?
No. We are not a law firm and do not provide legal advice. All legal services are delivered by licensed, independent U.S. immigration attorneys. Our role is to match you with the right lawyer and help organize your case materials.
Which visa types do you cover?
We focus on O-1A (extraordinary ability), EB-1A, and EB-2 NIW (National Interest Waiver) visas. These are the key categories for STEM professionals, researchers, and startup founders.
How long does attorney matching take?
Typically within 48 hours of completing your intake survey. You will receive a shortlist of vetted attorneys with transparent pricing and timelines.
What if I already have a lawyer?
You can still use our services. Our Case Readiness Pack helps organize your evidence and identify gaps, which speeds up the process regardless of which attorney you work with.
Can I use ImmStack if I already have a lawyer?
