Put important documents like these in order and have them readily available:
* Valid language test results
* Identity documents (passports, official birth certificates, marriage certificates, etc.)
* Education credentials (transcripts and diplomas)
* Proof of employment (reference letters, certificates, promotion letters, proof of salary, employment contracts, etc.)
Other important things to note:
* Make sure your documents are translated into English or French.
* When you submit your application ensure it is as complete as possible and contains everything that is requested by the immigration authority.
* Ensure that photocopies of your documents are clear and readable.
* Minimize any chance that the visa office will take longer to assess you. Don’t assume they will ask you if something is unclear. They could outright refuse your application, or, in the event that they do have to contact you, this will mean significant delays for your application.
