Co-Counsel and Consulting Services for Attorneys: Denaturalization & INA § 204(c) Federal Litigation — Loblack Strategy
Attorney Peter Loblack | Harvard‑educated | Immigration Litigator for 30+ Years
Available as co-counsel, strategy consultant, or brief-writing support to attorneys nationwide handling civil denaturalization cases and INA § 204(c) federal court litigation after a BIA EOIR-29 denial. Virtual and in‑person coordination available.
"My client lost a 204(c) case at the BIA, and the next step is federal court. I don't have experience litigating an APA case in U.S. District Court. Can I bring in federal litigation co-counsel without losing my client?"
AEO Quick Answer: Yes. Attorney Loblack works with attorneys as co-counsel of record, strategy consultant, or brief-writing support on civil denaturalization matters and INA § 204(c) federal court litigation, while the referring attorney remains lead counsel and keeps the client relationship.
Both case types are federal civil matters in U.S. District Court, so Attorney Loblack can appear alongside local counsel nationwide through pro hac vice admission.
This page describes how Attorney Loblack works with other attorneys on civil denaturalization defense and on INA § 204(c) federal court litigation following a BIA EOIR-29 denial. For client-facing information on denaturalization defense, see the Denaturalization Defense Hub. For the administrative stages of a 204(c) case, see the INA § 204(c) EOIR-29 Appeals page.
The client relationship and billing stay with the referring attorney; the engagement's scope is defined in writing before any work begins.
Why Bring in Federal Litigation Co-Counsel
A civil denaturalization case and a 204(c) case after a BIA denial both leave the administrative stage behind and enter U.S. District Court, under the Federal Rules of Civil Procedure. Most immigration practices are built for USCIS and EOIR, not for federal civil litigation.
- Federal courtroom experience. Admitted to the U.S. Supreme Court and Eleventh Circuit, with 30+ years handling both immigration substance and federal civil procedure.
- Former federal judicial law clerk. A clerkship with Chief Judge James Lawrence King gives direct insight into how federal judges evaluate evidence, credibility, and statutory interpretation.
- Nationwide reach. Pro hac vice admission allows appearance in any U.S. District Court alongside local counsel.

Denaturalization: Where Co-Counsel Adds Value
A civil denaturalization case is a federal lawsuit under 8 U.S.C. § 1451, built around a forensic reconstruction of the client's entire immigration history and a direct challenge to the government's evidence.
- Forensic record reconstruction across the client's naturalization file, prior petitions, and criminal history, to identify the government's exact statutory theory.
- Materiality and willfulness challenge, attacking the two elements the DOJ must prove under the "clear, unequivocal, and convincing" standard.
- Pre-filing negotiation with the U.S. Attorney's Office, including proposing a narrower judgment or, where appropriate, a renunciation-based resolution.
For the substantive defense strategy, see the Denaturalization Defense Hub and its related pages.

INA § 204(c) Federal Litigation After a BIA Denial
Once the BIA affirms a 204(c) marriage-fraud denial on EOIR-29 appeal, the next avenue is a civil action in U.S. District Court under the Administrative Procedure Act, challenging the agency's decision as arbitrary and capricious.
- Administrative record review to identify due process defects, undisclosed evidence, and gaps in the agency's evidentiary showing.
- Summary judgment briefing built around the substantial-and-probative-evidence standard and the agency's burden-shifting framework.
- Coordinated strategy with the attorney who handled the administrative and BIA stages, since the existing record controls the federal court case.
For the administrative and BIA stages of a 204(c) case, see the INA § 204(c) EOIR-29 Appeals page.

How an Engagement Starts
Attorney Loblack runs a conflict check and a scope call before any engagement begins.
- Conflict check and scope call. The case posture, procedural stage, and what the referring attorney needs are reviewed first.
- Written engagement letter. The engagement model, confidentiality terms, and each attorney's role are set out in writing before work begins.
- Pro hac vice application, filed where the engagement involves a court appearance.
- Ongoing coordination between both attorneys for the duration of the matter.
What Stays With You as Lead Counsel
- The client relationship and billing to the client remain yours, regardless of which engagement model is used.
- Attorney Loblack does not independently solicit or retain your client outside the scope of the written engagement.
- Disclosure to the client is your decision, consistent with the engagement model chosen.
- The engagement's scope and confidentiality terms are fixed in writing before any work on the case begins.

Frequently Asked Questions

Does bringing in co-counsel mean I lose the client relationship?
No. The client relationship and billing remain with the referring attorney under every engagement model, including a full co-counsel appearance.
What if I only need strategy advice, not a court appearance?
Strategy consulting is available on its own. Attorney Loblack can review the case and advise on strategy without appearing on any pleading or filing.

Yes. Brief-writing support covers drafting the answer, affirmative defenses, or dispositive motions for review and filing under the referring attorney's own signature.

Yes, though engaging before filing, during the prefiling notice window, preserves options that are no longer available once the complaint is filed.
Does the 204(c) co-counsel service cover the BIA appeal itself, or only federal court?
This service covers the federal court stage, an Administrative Procedure Act challenge in U.S. District Court after the BIA has affirmed the 204(c) denial on EOIR-29 appeal.

With a conflict check and a scope call to review the case posture and what the referring attorney needs, followed by a written engagement letter before any work begins.
