I am 4 months into a job situation here in Thailand and have received a visa and work permit for 12 months (which expire Jan 14. 2007).

I have decided that this job is not to my liking...my office already has possession of my work permit. If I quit, they want me to give them my passport so that they can cancell my working visa...and I will be left with 7 days to (on my own) get some type of new visa.

Question is:

What if I do not (perhaps I forgot) give them back my passport and move to a different part of the country (which I will)...and live on my current one year visa...

will there be any negative ramafications for me...?

You will be in serious trouble and you will be found out under the conditions described. You are required to visit immigration yourself if your employer does not do for you.

You will be in serious trouble and you will be found out under the conditions described. You are required to visit immigration yourself if your employer does not do for you.

Everyday past the 7 days, you will be fined 200 Baht per day for overstay. Additional 200 Baht fine per each family member over 14 years old that is a dependent on your extension of stay based on business. Maximum fine is 20,000 Baht for you along with a maximum fine of 20,000 Baht per family member. If found to be overstay, your family ( if you have one here as a dependent) and you risk being put in jail and deported.

Visa is contingent on employment - job ends visa ends. So in other words you can't gain benefit just because you pack your job in.

Your boss can report you to immigration, which would lead to all sort of problems. Unless you don't want to stay in LOS long tem you should get your visa cancelled.
