I am a citizen of Pakistan currently working in the UAE. Can I apply for immigration in Islamabad and have my interview in Abu Dhabi?
As a Pakistani citizen, you can apply to the Islamabad office no matter where you live. If you have been lawfully admitted to the UAE as a foreign worker on a work permit, and you have been living there for at least one year, you can also apply to the Canadian Embassy in Abu Dhabi. However, you cannot apply at one office and ask for an interview in another one. You should decide which of the two offices is more convenient for you and has better expertise to assess your education and work experience. Files are not transferred from one office to another.
