I have been offered a job in Singapore and recently made a trip there thinking I could speak to my potential employers face to face. But I was rejected entry into Singapore for unknown reasons. They refuse to let me know why and I had to board a Plane back to Korea.
I have since accepted the job and have gotten my approval on my work permit.
However, I worry if there will be any issues again with regards to my entry.
I want to avoid a repeat incident as the previous one has left an unpleasant taste.
Does anyone know what I should do to be sure it won't happen again?
