Questions
Before you begin
What founders ask before forming a U.S. operation from abroad.
No. You can form a U.S. company from any country in the world. We handle the entire process remotely — formation, EIN, registered agent, banking application — without you setting foot on American soil.
Most founders we serve form an LLC for its simplicity and pass-through taxation. A C-Corp is the right call if you intend to raise venture capital from U.S. investors or issue stock. We will recommend the entity that fits your business model, not the other way around.
We typically deliver your formed entity in five to ten business days, depending on the state. Florida, Delaware, and Wyoming are the fastest. Your EIN follows within two to four weeks.
Yes. We prepare your application, introduce you to our banking partners, and walk you through the onboarding. Most of our founders open their accounts entirely online — no flight required.
Yes — every U.S. company needs both to satisfy federal banking and tax filing rules. With the Growth Plan we handle that logistics for you: a registered U.S. business address held in your company's name, full mail handling, and a dedicated U.S. eSIM line ready to activate on your own device. No relocation required.
An EIN is your company's tax identification number — required to open a bank account, hire, or file returns. We file it for you. An ITIN is a personal tax ID for non-residents who receive U.S.-source income; we file it when your situation calls for it.
Not if your structure and tax position are set up correctly. The United States has tax treaties with most major countries. We structure your company to avoid double taxation and coordinate with your local tax advisor.
Yes. We open your merchant services account so your business can process American card payments from its first sale, alongside your bank account.
Yes. Every conversation, every document, every filing — bilingual from the first call to the final return.
