Honest about a weak case

Other lawyers wanted to take my money. They told me to wait six months and refile — and that's exactly what worked.

Won my asylum case after 4 years of waiting

I was nervous after switching from a previous lawyer, but everything went smoothly. They prepared me for every question the judge could ask. Got approved last week — still can't believe it.

VAWA approval — they treated me like family

Could not have done this without them. They listened, never judged, and got it done.

Transparent, calm, and incredibly thorough

Walked me through every step of my I-130. Replied to every email within hours. Worth every dollar.

Patient and bilingual — explained everything in Spanish

Mi mamá pudo entender todo el proceso. We never felt rushed. Highly recommend.

Frequently asked

A 30-minute video or phone call. We review your situation, identify the best path, outline timelines and costs, and answer your questions. You'll receive a written summary afterwards.

Most cases are flat-fee. Pricing depends on category and complexity, and is shared in writing before you retain.

Only the initial consultation is paid through Immigrantio (via Stripe checkout). Once you retain, the lawyer bills you directly — retainer, milestone or hourly fees go straight to the firm's own trust account. Immigrantio is not in the chain of custody for case payments.

Conversations on Immigrantio are end-to-end encrypted. For sensitive case documents and original evidence, you'll exchange those directly with the lawyer by their preferred secure method — Immigrantio doesn't store your case files.
