yeah. You leave the train go through border. Get both stamps. Go upstairs. Buy the next train ticket and wait about 30minutes or so. Its much better than the van. And much cheaper. The whole train trip with the ferry will cost about 240 baht. Van are between 400 and 800 baht. Vans I dont really like because every place that sell tickets have different times and different prices.
I live in Hat Yai so found the information at the train station and I go to Penang every 3 months. There is 1 train that is specific just for hat yai - pedang besar twice a day.
Trains from Hat Yai to Pedang Basar is at 07:25 and 13:00 only. 2 trains per day. Trains to Butterworth runs every 2 hours. The Thai consulate wants all the docs including 2 police clearance checks. 1 from your home country and 1 from Thailand. If you go in person there make sure you get there early as they only accept 100 applications per day. And yes just carry 20,000 baht on you when coming back to Thailand.
This form is the WP3 form that has to be filled out and handed in at the Department of Labour. Then you will get a document from them that states that you have applied for your workpermit and that form goes to the Thai Consulate.
Amber, Did they take your documents or just flat out reject you on the ? I am in the same situation as you. Us citizen, been here 3 months, i have a criminal check from the usa, all of my paperwork expect the thai crimial check
