ILR appliction query

[palack123]

HI,

i have couple of queries on my ILR application.

Below are the main dates related to my immigration –

20th Nov 2009 – Tier 2 ICT Visa got stamped.
15th Dec 2009 – Entry to UK
31st Dec 2012 – Got Tier 2 ICT converted to Tier 2 General Visa - granted ( No Breaks in Visa ) till Jan 28th 2016

1. Will I have to mention the time period between 20 Nov - 15th Dec as being absent from UK and what would be the
justification I would need to provide. And will this be counted as the number of days absent out of UK.
2. What is the date which I need to mention on 6.1 section of Set O form. IT says - When did you first enter the UK ?
This refers to the date of your first entry into the UK at the beginning of the period of stay on which this applicaiton
is based ? Should I mention 15th Dec or 20th Nov. And if I mention 15th Dec, it might consider me eligible 28 days before
15th Dec.

Thanks.
