@Bobby *******
When I say "right thing" I mean legitimate style visas such as ED and Non-O/Non-Bs. The government recommended people to either 'prepare for leaving' or to arrange appropriate visas, and immigration offices came up with ways (price permitting, even for legitimate cases) to swap without leaving the country.
It's been totally unclear and there were even times when the papers were running messages saying things like "get out by X September or face fines and further issues".
