Evidence of Work Related Absences

[magelenn]

Hi, im now collecting all the documents for my upcoming ILR application. Can anyone please advise me what serves as an evidence of work related acitivities? I attend a lot of trade shows as a Sales Director, would old event's badge be an evidence or it should be a plane ticket or a boarding pass?
Or is an email confirming my absence enough?

Many thanks,
Magelenn

You could obtain letter from your employer detailing all your work related absences and that you are paid during these trips
