StunningTurtle691 no you cannot go from an extension of stay back onto a Non-O in country, you have to leave and either get your Non-O elsewhere or re-enter on a tourism stamp and convert to a Non-O
StunningTurtle691 If that lapse was in the first 3 months of your current extension you are likely to be refused a new extension and will need to leave at some point to start with a Non-O again.
If you are applying for an extension that might require an under consideration period and house visit then that might overlap your travel plans so please tell us the reason for the extension
