Yes. New Mexico allows non-US residents to form a S-Corp entirely remotely. You need a registered agent with a New Mexico address, and you'll apply for an EIN from the IRS using Form SS-4.
No. You can form a New Mexico S-Corp from anywhere in the world. However, you must maintain a registered agent with a physical New Mexico address.
Standard processing: 1–3 days. Expedited processing is available for an additional fee through the New Mexico Secretary of State.
Mercury and Relay are the top choices for international founders. Both open accounts fully online, require no US visit, and work well with New Mexico entities.
