Need US Corporate Banking & Check Processing Consultation for Non-Resident LLC

I run a Montana-registered US LLC as a non-resident and I am holding a physical commercial check that names only my company as payee. Relay, my former digital bank, closed my account, and every other fintech option I have contacted rejects applications without an SSN. The issuer of the check will not re-issue it electronically, so my immediate priority is to get these funds legally deposited into a business account while I remain outside the United States.

You will advise me on a workable, compliant path that lets a non-resident LLC:

• deposit this specific check, and
• if necessary, open or access a traditional U.S. business banking channel remotely.

I can supply the LLC formation documents, EIN confirmation letter, and my passport scan. I need to understand any other paperwork, endorsements, courier steps, correspondent banks, or third-party services that would satisfy U.S. anti-money-laundering and KYC rules without my physical presence.

Your guidance should outline:
1. the exact bank(s) or service(s) willing to onboard a non-resident LLC under these conditions,
2. step-by-step application or mailing procedures,
3. expected verification hurdles and how to clear them,
4. timeline and approximate fees, and
5. any risks or compliance caveats I must consider.

Please respond only if you have first-hand experience solving similar non-resident U.S. LLC banking or check-processing challenges and can reference that experience during our consultation.
