* Ideally, you should provide letters of reference from your current and past employers. These letters should be on company letterhead and signed by the appropriate individual. The letters must include your period of employment, positions held, duties, salary, hours of work, and a business card of the person signing.
* If you can not provide all of the above, you must include an explanation in your application why not. If you do not have (or can not get letters of reference), the next best thing would be to provide old contracts of employment with your employers, or old performance appraisals, etc.
* If you can not provide any of the above, your application may be in jeopardy. If you can find an old supervisor or even work mate, he or she could swear an affidavit on the above details of your employment to help support your application, along with your own explanation and description.
* At this point, you will have to get creative about documenting your work experience. Are there any third-party publicly available documents about you on the web you can point to? Any news articles? Association newsletters?
* Emails from work proving my job type
