How we work

1.

Consult

Meet a citizenship and immigration lawyer for 30 minutes. We review your family tree, confirm whether you qualify, including under Bill C-3, and give you a clear legal strategy. See what to expect.

Consultations are booked first come, first served and the consultation fee is credited toward our flat fee if you retain us. Our next available consultation is currently within 5 business days (as of October 2026).

2.

Research and prepare

You work with Cédric Marin and an associate lawyer, who prepare your forms and legal submissions.

On citizenship by descent files, our in-house genealogist traces your lineage and orders the records. See what sets us apart.

3.

Review and file

A lawyer who has not worked on your file reviews it the way an officer would, then Cédric Marin signs off and we file with IRCC.

We cover the mailing, resubmit at no charge if IRCC returns the application as incomplete, and stay with you until a decision. Read our promise to clients.
