Yes. New Mexico allows non-US residents to form a C-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 C-Corp from anywhere in the world. However, you must maintain a registered agent with a physical New Mexico address.
