The price of every stage is already on this site, so a first call is about fit — not a pitch.
Stage 2 · Foundation
Your U.S. base, done for you: entity, EIN, ITIN, bank introduction, address and phone. In your name, yours to keep, from the first week.
A properly formed LLC or C-Corp in the right state for your situation, a federal EIN, an ITIN applied for in your own name through a Certifying Acceptance Agent (no passport mailing, ever), a U.S. bank account introduction, and a working U.S. address and phone presence. Everything is registered in your name — Keystone never holds your assets.
The ITIN is the key that unlocks the U.S. personal credit system for non-residents. Without it, you're locked out of the credit-building path that makes the rest of the ladder possible. We process it through a Certifying Acceptance Agent so your passport never leaves your hands.
Formation typically completes in 1–3 weeks depending on the state. ITIN processing is controlled by the IRS and routinely takes 7–11+ weeks. We control submission quality and follow-up — not the IRS calendar — and we tell you that upfront.
Whether your home country has a US income tax treaty changes the withholding analysis on payments your LLC receives. Check the verified reference table before you form.

For founders who want the tax ID before committing to full formation — applied for in your own name through a Certifying Acceptance Agent, no passport mailing.
What we never promise
We never promise IRS timelines. The ITIN calendar belongs to the IRS; our commitment is submission quality, follow-up, and honest status updates at every step.
