>What would be the consequences of delaying the extension?
I believe *COMPANIES* are separate legal entities to the business owner. However, if you delay renewing your extension of stay, you will be fined 500THB a day, with a maximum fine of 20K THB. If you are overstay longer than 90 days, OR caught while on overstay, you will be blacklisted for 5 years.

> Would I just lose my visa
Keeping it simple; You would lose your visa (or, technically, your right to stay in Thailand on your existing stamp)/ extension of stay, and you may have to restart the process over (leave Thailand, get the paperwork for the visa, re-enter..)
>Would that cause immigration officials to visit my office?
I understand you can not work while on overstay. If you are caught, you will be blacklisted for 5 years.
>Would I be a able to apply for the visa later?
If you are blacklisted, you can not enter Thailand for 5 years.
