ILR Section 6 Immigration History

[sdr]

Hi
For Section 6 ( When did you (the applicant) first enter the UK etc)

I was granted a Tier 1 General and came to the UK in July 2010.
I was in and out of the UK until got a perm job and entered the UK in March 2011.

Do I use July 2010 or March 2011?

Thanks
