Am now in the process of applying for my ILR after my employer agreed to provide the Employment Letter. In addition, i have come up with a list of absences from the UK since 07.2013 and have the following in total:

• 44 days of paid leave (holidays to different countries
  17 days Unpaid leave as i took holiday before commencing a new role with another organisation
  9 days of work trips in Europe with my previous organisations

Total number of days out of the UK on holidays and work trips is 70 days for the past 5.5years.

My question is, do i need to provide any evidences of these list of absences since they are less than 180 days in each year? And since i have left my previous organisation, do i need to get confirmation from my previous organisation for the work trips i was away from the UK?

Please help!!
