Do you know if there are any other FT's who have been teaching there illegally at first on L visas,even just for a day?I'd be willing to bet that there are.Looks like you're in a corner.It would be good to dump the TC deeper in the mire by reporting the other FT's who've been teaching on L's at one time or another too when you turn yourself in.I reckon that'll deflect the attention of the police from you to some extent.As for that racist TC,it'll be fined an arm and a leg,and forced to close down,the owners likely to be jailed too.Forget telling your country's embassy.They can't and will not help you.But can you amass sufficient funds to pay a 5000 Yuan fine to keep you out of jail,and buy an air ticket to exit the country,quickly enough before you've exhausted your visa rights?Looks to me you're in a jam.But you can spread the blame if they won't co-operate.Obviously time is of the essence.You'll be able to get a 10-day extension by applying for a new L just before your present one runs out.Be careful not to overstay your visa,the fine would be 500 a day up to a maximum of 5000 when the PSB catches up with you,and you'll also have to have the necessary funds to exit the country!
