In my experience, you are FAR less likely to get stuck in an appeal loop with 70IQ foreigners reviewing your documents if you first purchase a G-Suite email for $8. (I can't tell you how many times I've had documents rejected multiple times before getting approved after simply re-submitting the same correct document. It's maddening with some of the Angi-list type places that constantly have to verify licensing.) I currently have 5 tied to an old Gmail account. I recently tried to open one on that account for a local painter from my church and we have been fighting the verification process for months. The other day I opened another one with a G-Suite email (still tied to the same address) and it opened instantly with no problems. And you can always cancel the email address once you have it processed.
