Sorry for reply late I'm very busy. As your requirement to issue work permit for you to maintenance 10K. Firstly We would like to know, how come for entering into maintenance this time need issuance for work permit since in the past we never issue work permit thus maintenance services only for a short period of time. In addition, applying method of work permit is complicated and take long time and we never issue work permit before so please explain the reason for us thank you.
