Bring the employer's support letter, citizenship proof, the qualifying degree or licence with any evaluation or translation, and evidence of the current relationship with the employer. Organize them so an officer can follow the case in minutes.
Build the file in the order an officer reads it
The first page should be the support letter, because it tells the officer what profession is claimed and why. Behind it place the passport and citizenship evidence, then the credential, then anything that bridges a gap: a credential evaluation for a Québec diploma whose title does not translate obviously, a French-to-English translation of a transcript, or an order's confirmation of good standing. Hypothetical example: a Lac-Beauport applicant holds a baccalauréat from a Québec university whose transcript lists courses only in French.
An officer is not obliged to read French, so a certified translation prevents a refusal based on a document nobody could assess. Add a short résumé that matches the dates in the transcript and the employer's letter, since inconsistent dates invite questions. Keep the whole file in paper form; a phone screen is not a document.
Do not include unrelated material such as property deeds or bank statements, which suggest an intent the category does not require.
