Federal immigration counsel for professionals, families and companies building their future in the United States — EB-1A, EB-2 NIW, O-1, L-1 and family-based petitions.

The Firm

A practice limited on purpose

C2K Immigration Law PLLC is a boutique law firm dedicated exclusively to federal immigration counsel. We prepare petitions for professionals crossing into their next chapter in the United States — researchers and physicians pursuing EB-1A and EB-2 National Interest Waiver, executives on L-1 transfers, artists and specialists under O-1, entrepreneurs relocating under E-1 and E-2, and families reunifying under family-based visas.

Federal immigration is a discipline of documented evidence, procedural rigor and long-view strategy — and we believe those matters are best served by a firm that does nothing else. Every petition we prepare is built as a case that must persuade, not merely comply.

The firm's principal office is in Orlando, Florida. We serve clients in English or Portuguese, remotely or in person, with the same technical standard in either language.

Rigor

Evidence organized against the applicable regulatory criteria.

Focus

Federal immigration only. Nothing else competes for attention.

Candor

An honest reading of your odds, before you commit.

Practice Areas

Matters governed by federal law

EB-1A

Extraordinary Ability

Permanent residence for those at the top of their field, documented against the criteria at 8 C.F.R. § 204.5(h). No job offer required.

EB-2 NIW

National Interest Waiver

For advanced-degree professionals whose work carries substantial merit and national importance, structured on the Matter of Dhanasar framework.

O-1

Extraordinary Achievement

Temporary work visas for extraordinary ability in the sciences, business or athletics (O-1A), or achievement in the arts and film (O-1B).

L-1A / L-1B

Intracompany Transfer

Transfers of executives, managers and specialised-knowledge employees, including new-office petitions for a first U.S. presence.

E-1 / E-2

I-130 / I-485

Family-Based Petitions

For spouses, children, parents and siblings of citizens and permanent residents, including adjustment of status and consular processing.

N-400

Naturalization

U.S. citizenship applications, including continuous residence, physical presence, good moral character and the effect of extended absences.

Marcelo Barros da Cunha

Founder & Managing Member · Attorney at Law

A lawyer and engineer admitted in New York and in Brazil, Marcelo has practised law for more than twenty years at the intersection of regulation, infrastructure and complex project structuring. Much of that path was built at Brazil's Federal Court of Accounts, where he served as advisor to a Justice, head of audit and legal counsel to the Presidency — scrutinizing privatizations and concessions and defending the Court's institutional powers before the Supreme Federal Court. At the Presidency itself he led the Transport Coordination of the Investment Partnerships Program, steering port, highway and railway projects of national reach. He holds an LL.M. from Harvard Law School and is a doctoral candidate in constitutional law.

That background shapes how he practises immigration. An EB-1A or EB-2 NIW petition is a case built on documented evidence and structural argument — the same discipline he brought to constitutional and regulatory work. Clients receive petitions written with an argumentative rigor uncommon in high-volume immigration practice.
