Can a non-US resident get an EIN?

Yes, non-US residents can obtain an EIN from the IRS.

You do not need to be a US citizen, permanent resident, or have a Social Security Number. The IRS issues EINs to any entity that conducts business in the United States, regardless of the owner's nationality or residency. Non-US residents must apply using Form SS-4 submitted by fax or mail since the online application requires an SSN or ITIN. You will need to designate a "responsible party" on the form, which can be yourself even as a foreign national. Your foreign passport number serves as your taxpayer identification for the application. Many international founders form a US LLC or C-Corp and then obtain an EIN as part of their formation process through services like Lovie.
