Don't believe you mean come in on a "visa on arrival" there

I think what you really mean is come back on a free 30 day "visa exempt" entry <-(which is not a visa on arrival, in fact, not a visa at ๐ฎ all just a free entry stamp ๐ )
You're unlikely to get questioned about it and if you did get questioned you would just say you're between jobs and are waiting for new Non-B documents <- which is true ๐
