My major responsibility was to write and correct the document that about the thai export/import regulation. I had learned more about regulation and law, which is usually useful in the future. I had discovered that in order to write a formal letter or governor document, it was not easily as it looked, because everything need to be precise and specific. They had to re-check more than 3 times to release the final announcement. However, this was not the only job that I done during my first month. Furthermore, I had coordinated with the head quarter of the Thai Custom department about VIP customers, regulation, decay of product, and export/import activities. AOT also one of another company that Thai Custom department had to work with, because they control everything inside the airport and we had to ask for a permission to work.
