Combining Tiers

[profusion]

Hello

I have resided in the UK since 2012 with the following visas:

2012 - 2013: Tier 4 (General) student
2013 - 2015: Tier 2 (General)
2015 - 2017: Tier 1 (Graduate Entrepreneur)
2017 - Present: Tier 1 (Entrepreneur)

My understanding is that the student visa cannot count under any circumstances, however can any of my previous working visas be combined with my current Tier 1 (Entrepreneur) visa to qualify for ILR after 5 years (in 2018)? There have been no breaks in the continuity period.

No. Time spent on Tier 2 or Tier 1 Graduate Entrepreneur does NOT count towards the specified period required for ILR under Tier 1E.
Under Tier 1E rules, the specified period for ILR must have been spent with leave as a Tier 1 (Entrepreneur) Migrant only.
The specified continuous period is at least at least 3 years under accelerated settlement route and 5 years in all other cases.
