I plan to apply for the Non-O Retirement e-visa outside Thailand. I will enter Thailand using this e-visa, open a Thai bank account, transfer THB800,000 (or more) from my non-Thai overseas bank into my Thai bank account to season it for the extension application.

During the initial 90 days, can I travel back to my home country, or do I have to stay in Thailand until my extension application is completed? If I can travel back, do I return to Thailand using the first Non-O e-visa or come in on visa exempt ? Thanks

Update : Thanks for the helpful comments. Will get the re-entry permit so I can leave Thailand during the initial 90-day e-visa period (will check with Immigration office if this is possible too).
