One firm, one engagement, one point of contact

International moves usually involve several systems at once: U.S. immigration agencies, a U.S. consulate, civil registries in the home country, and sometimes a foreign court, tax office or immigration authority. The hardest part is often keeping everyone aligned. Our model is built to solve that.

U.S. law, handled directly

Our attorneys prepare and file your U.S. immigration matters before USCIS, the Department of State and U.S. consulates, and advise on the U.S. business structure behind an investor or transfer case.

Local counsel, coordinated by us

When a matter needs advice or representation under another country’s law, for example a foreign residence permit, a local court record or a corporate filing abroad, we coordinate with attorneys licensed in that country. We do not practice foreign law ourselves.

You keep one relationship

Ozek Law remains your single point of contact and your engagement is with our firm. We brief local counsel, track their deliverables against your U.S. timeline, and report back to you in one place.

Ozek Law Firm attorneys are admitted in Maryland, New York and the District of Columbia. California matters are handled with California-licensed co-counsel. Immigration law is federal, so we represent immigration clients across the U.S. and worldwide.

Türkiye matters

Serving Turkish-speaking clients is at the core of our practice. Our founder, Tolga Ozek, holds an LL.B. with honors from Bilkent University and an LL.M. from Duke University School of Law. Attorney E. Gizem Ersahin is admitted to the New York Bar and is also a member of the Istanbul Bar in Türkiye, which gives our team first-hand familiarity with Turkish documents, institutions and business practice. Where a matter requires representation before Turkish authorities, we work with licensed Turkish counsel as described above. See our Türkiye and U.S. immigration guide for details.

How cross-border work runs

Video consultation

We schedule across time zones, from Istanbul and Stockholm to Dubai and Mexico City, and map every route that fits your goals, including the documents each country will ask for.

Engagement and onboarding

Engagement documents are signed electronically and payments are made online. You receive access to our secure client portal for document upload.

Coordinated timeline

We build one plan that sequences U.S. filings, consular steps, foreign civil records, translations, apostilles and any local counsel work, so that nothing expires while something else is pending.

Preparation and filing

We prepare the forms, evidence and legal arguments, review everything with you, and file.

Follow-through

We track the case, respond to routine requests, prepare you for interviews, and keep you updated by email, phone or WhatsApp.

Dual citizenship and second passports

Which passport you hold can change your U.S. options. Treaty investor (E-2) eligibility depends on nationality: the investor must be a national of a treaty country, and at least 50 percent of the business must be owned by treaty nationals. Türkiye and Sweden, for example, are both E-2 treaty countries. The Department of State’s guidance says that a dual national owner must choose which nationality to use for E visa purposes.

A second citizenship can also affect visa waiver eligibility, travel restrictions that apply to certain nationalities, and the documents a consulate will require. Tell us about every nationality you hold, including one acquired by descent, so that we can compare routes. If you are considering a second citizenship for U.S. planning, we review the U.S. immigration consequences; questions about the other country’s citizenship law go to counsel licensed there, and tax questions go to a qualified tax adviser.

Common problems we help prevent

  • Foreign civil documents that do not match what the consulate or USCIS expects, or that lack a certified English translation.
  • An apostille obtained from the wrong authority.
  • Expired police certificates or medical exams while another step is still pending.
  • Advisers in different countries giving advice that does not fit together.

Useful tools: Ozek immigration tools, the green card travel checker and the citizenship eligibility calculator.

Frequently Asked Questions

Global Immigration Services: Frequently Asked Questions

What does a single point of contact mean in practice?

Your engagement is with Ozek Law Firm, and we are the team you talk to. We handle U.S. immigration law directly and, when a matter needs a lawyer licensed in another country, we coordinate that work and report back to you, so you do not have to manage several firms yourself.

Do you practice the law of other countries?

No. Ozek Law Firm attorneys are admitted in Maryland, New York and the District of Columbia. When foreign law is involved, we coordinate with attorneys licensed in that country.

Can you represent me if I live outside the United States?

Yes. Immigration law is federal, so we represent immigration clients across the U.S. and worldwide. Most international matters are handled by video consultation, secure upload and electronic signature.

Which languages do you work in?

Consultations are available in English, Turkish, Spanish and Swedish. We arrange interpreters for other languages.

Does my second passport matter for a U.S. visa?

It can. E-2 treaty investor eligibility depends on nationality, and dual nationals must choose which nationality to use. Other rules, such as travel restrictions, can also depend on nationality.

Is Türkiye an E-2 treaty country?

Yes. The Department of State treaty table lists Türkiye (shown as Turkey) as an E-1 and E-2 treaty country. Sweden is also listed for both.

How long will my case take?

Government processing times vary by agency, consulate and case type, and they change. We do not promise processing times, but we plan the steps so that documents stay valid and nothing waits on avoidable delays.

How much do your services cost?

Scope varies from matter to matter, so we give a fee quote at consultation. Government filing fees are separate.
