The new office will open on March 1 near the passport office in Zone A on the fifth floor of the mall, deputy government spokeswoman Traisulee Taisaranakul said.
The office – which can notorise documents – will be fully functional for both Thai and foreign nationals in Bangkok, Traisulee said.
It will be easily accessible by public transportation and private vehicles, she added.
The Khlong Toey office will receive applications and documents for the last time on Wednesday and return documents on Friday, she said.
If the people fail to collect their documents by Friday, they must subsequently contact the MBK office to obtain them, Traisulee added.
The new office will be open from 10am to 4.30pm on weekdays.
