Yes it is always a worry.
Anyway there is nothing stopping your girlfriend from walking out the door once you have brought her to your home country. Many have done so!
Legally she cannot get a job as she is only on a tourist visa. and would be in the country illegally if she overstays her visa.
You cannot make her leave before her time, all you can do is report to the authorities that she has disappeared, and hopefully they will find her and deport her back to where she came from!
You maybe liable for the cost of this as you are her sponsor! grin
I know a thai lady from Pattaya that got a visitors visa to come and see her boyfriend, (in England). She phoned me before she was leaving Thailand and wondered if I could pick her up from the airport as she did not love her boyfriend and wanted to stay with me for her visit!

its terrible how bad the phone connection can be sometimes between Thailand and Britain!
