I had the 500k bhat in the last month, but provided 6 months of statements. Was approved for Muay Thai in Hanoi, Vietnam. Unfortunately, I don't know the specific requirements for French Consolate. Be sure to have a letter from your superior specifically stating that you have permission to work from Thailand.
Anonymous participant you are not a customer. You are an applicant that didn't get what he wanted. You are not paying for a visa, you are applying for a visa. There's a difference.
The fee is nonrefundable. You are taking the risk of losing your money if you don't have everything in place, and meet all requirements. The consolates have limited staff to process these applications and they don't have time to hold your hand through the process. If you give them everything they require in the original application, they won't need to ask for further documents and you will be approved sooner.
You need certificate of residence from immigration (get this with your tm 30 from lodgings)- do this first, as it can take time to process, only at the airport immigration office in the morning, they are closed in afternoon. Get medical certificate. Bring these 2 letters to driving school. Pass the course, then take the passing letter from driving school to department of land transport to get your license.
