Dated letters from each employer describing the properties, the responsibilities held and the exact periods worked, together with the diploma and its transcript. Where the applicant was the owner-operator, corporate registry records and payroll filings do the work an employer letter would otherwise do.
Experience is proved by other people's records, not by a résumé
A curriculum vitae asserts a history; the file has to evidence one. For each period Imelda relies on, the strongest document is a letter on the employer's letterhead giving her title, her dates, the size and type of the property, and the responsibilities she genuinely held, signed by somebody able to speak to them. Where an employer no longer exists, payroll records, T4 slips or a letter from a former supervisor identifying their own role can fill the space.
Where she managed a property she partly owned, the registry filing and the company's payroll returns establish the same facts. The diploma should be produced with its transcript rather than on its own, because the transcript is what shows the programme was in hotel or restaurant management. Anything not in English needs a complete certified translation.
Arrange the periods chronologically so that three qualifying years are visible without anyone having to reconstruct them.
