How can we extend our non-O and non-B visas in Thailand?

Linda, your husband could do this himself but most companies have at least a contract accountant which is actually a necessity for required monthly and yearly reports that form the basis of the required documents to get another extension of stay. In no way is a lawyer required with the exception of original company formation. Hiring an accountant by contract is a normal business activity here in Thailand. An accountant can get all original company records from the DBD (Business Department, the Revenue Department, the Social Security Tax Office and perhaps the Ministry of Labor (Work Permit). These Departments can also provide copies of all required monthly reports and payments such as the Social Security "Social Fund" tax payments made by the 15th. of each month (paid at an authorized bank normally), the Revenue Dept. will have copies of the salary tax payments on your husband's required salary (PND1 and PND91) and Company tax payment reports. You will also need a copy of last year's Balance Sheet (a required Audited financial report). An experienced Accountant can find and assemble a document packet required for a new Extension of Stay. And usually at a price much lower than what a lawyer charges (the lawyer likely hires an accountant to do this and tacks on his/her lawyer fee.)

Visit the Immigration Office and ask the hand out with requirements to apply for a new Extension of Stay based on Working for your husband and for you based on being his dependent. Start making the copies and you can apply by yourself.

Hi Linda, does your husband have a non immigrant B multi entry visa, where he has to leave the country every 90 days?
