Obtain EIN for Non-US Resident

I’m setting up a U.S.-based business as a non-resident and need an experienced professional to walk me through getting an Employer Identification Number. This is my first time applying, so I’m looking for someone who can take charge of the entire process—from choosing whether to call the IRS or fax Form SS-4, to tracking the request until the CP 575 confirmation letter is in my hands. Here’s what I need from you: • Prepare and submit (or guide me in submitting) Form SS-4 using the fastest, most reliable option for foreign founders. • Keep me informed of expected time frames at each stage and handle any follow-up calls with the IRS if delays occur. • Forward the official CP 575 notice to me electronically, then by mail if required for account verification. • Explain next steps for opening a Mercury business banking account so I can pass their compliance review smoothly. Acceptance criteria • Valid EIN issued and verifiable on the IRS system. • Copy of CP 575 delivered. • Clear, written checklist for Mercury approval that I can follow without additional help. If you’ve helped other international founders secure an EIN and open Mercury accounts, I’d love to hear about your approach and typical turnaround times.
