What foreign founders need solved
Most non-U.S. founders need to incorporate a Delaware C-corp or Wyoming LLC, obtain an EIN (without a U.S. SSN), set up a U.S. bank account, qualify for treaty benefits where applicable, and stay compliant with both U.S. and home-country reporting obligations.
EIN without SSN
The EIN application (Form SS-4) can be submitted by non-U.S.-residents via fax or mail with the responsible-party section appropriately populated. IRS processing takes 4–6 weeks. AION handles the application end-to-end and tracks the IRS acknowledgement.
- Form SS-4 prepared and submitted via IRS-preferred channel
- ITIN application coordinated when needed for tax filings
- Treaty residency analysis for income-tax purposes
- Form 5472 / 1120 filings for foreign-owned single-member LLCs
U.S. bank account
Most U.S. banks require an in-person visit by an officer to open an account. AION has working relationships with banks that support remote opening for foreign-founder accounts, and we coordinate the application package (entity docs, EIN, beneficial-ownership disclosures) to maximize approval likelihood.
Korean-specific considerations
For Korean founders specifically, AION's Seoul-based team handles coordination with Korean tax (NTS reporting, treaty positions), local counsel for Korean entity coordination, and the operational reality of running a U.S. C-corp with Korean management. We do not outsource this knowledge.
