Yes, I'm talking about cancelling the extension based on a Non O. I've never heard of anyone penalised, but I was also surprised that the Non O extension needed to be formally cancelled at all. If approval is required to cancel it, then don't immigration need to check the conditions of stay have been complied with (that the monies have been deposited throughout)? There's a thread on a private Elite Facebook group that's discussing this right now which states that showing up to cancel the Non O extension requires bringing the up to date bank information, and the same is true of the two links I've attached. For certain there won't be problems with the bank regarding moving the money out, but will there be a problem showing up later with an unfunded period of time on the extension at immigration?
