Hi guys

Please help with my situation. Your help are very appreciated

Background

I came into England at year 2000 as a student and Switched to tier 1 dependant visa(entry clearance) on 04.2009. I have applied for the SAR report to check wether I continuously lived in the country or any gaps there at year 2010. As soon as the report came back and I noticed that In the personal notes under CID section shown local immigration team requested my ho files by one of their chief immigration officer on date 10.2009 and the files received by them on 03.2010. After that I have not applied ILR under 10 years route, at year 2012 I have extended my visa by another two years.

Question is
1. Anyone come cross this before? Any experience about this(your ho file been request by local immigration team?

2. What could it be for LIT requesting your files?

3. It is 3 and half year now Since LIT requested my file, nothing happen to me and also got visa extension successfully. Depending on this do you think it will effect me when I apply ILR at 2014.
