Immigration Law
Denver immigration attorneys - Building Relationships Across Borders
The Law Office of Catherine Brown, LLC is a full-service immigration law firm located near Boulder Colorado in the northwest Denver metro area, owned by Denver immigration attorney, Catherine O Brown. We assist our clients with obtaining temporary and permanent visas (green cards) in both the business and family settings as well as US citizenship.

Is your firm willing to help a client with one discrete part of a case, without taking on the whole case?

Yes but it depends on what type of case and the facts of the case. It would only happen if the potential client at least engaged in an initial consultation before the attorney would agree to partial case work.

What are your policies about dividing work within the firm to make the process most cost-effective for the client?

Our fees are a flat rate so there is no cost efficiency for giving work to a paralegal versus an attorney. The attorney always is responsible for legal advice and drafting of legal memorandum and correspondence with USCIS. Our paralegals assist primarily with completing immigration forms and obtaining the necessary documents from the client.

How frequently does your firm use mediation, arbitration, or collaborative law to resolve cases?


Does your firm provide pro bono legal services or otherwise participate in your community?

We provide low-bono services to those who are refugees or asylees. We do various pro-bono services throughout the year, including citizenship drives, serving on bar association committees, etc.

What distinguishes your law firm from others?

We strive to obtain the goals of our clients but in a personable and affordable manner. We get big law firm results in a small law firm context.

What is your firm's point of view regarding clients educating themselves on legal issues?

We understand that immigration law is very complex, quickly changing, and non-transparent to the public. Part of our services is educating our clients on how the rules work and how the process works regardless of the rules. We also keep our clients updated on changes to the law which can happen frequently in immigration law.

Is your firm willing to review documents prepared by clients?


Is your firm willing to coach clients who want to represent themselves?

Yes, depending on the type of situation. We can provide initial consultations or ongoing consulting work as needed.
