Longer UK absence during 5 years continuous stay

[aj80]

This query is regarding my ILR eligibility with longer UK absence of more than 6 months during my 5 years living in UK. I entered UK in Feb 2007 under Tier 2 category and later switched to Tier 1 category on Apr 2009. Tier 1 visa was granted while I was living and working in UK.

UK Absence Summary: (Longer UK absence marked in red)

a) 22nd Mar 2008 to 31st Mar 2008 = Paid vacation 8 days

Longer Absence Explained (point c and d)
Due to the project requirement the company requested to travel abroad (India) on 8th Jul 2009, unfortunately this abroad assignment extended beyond 20th Nov 2009. This resulted in a UK absence but employed and payroll under UK employer. As the project uncertainty increased, the company moved my payroll to India effective from 21st Nov 2009. Combination of travel abroad and later relocation has resulted in a UK absence of 220 days (Point c).

To establish my living in UK, I entered UK on a short visit between 14th Feb 2010 and 21st Mar 2010. After a brief vacation (point d) resumed my living and working in UK from 17th May 2010 onwards.

I would like to seek guidance from this forum on whether my ILR application may have slim chances of UKBA’s consideration given my absence history and circumstances. If there is no scope for my ILR application as UK absence in 5 years period is bursting the threshold, is it safe to start counting 5 years continuous stay from 21st Mar 2010?.

Thanks Mehta. Just to summarize on the long gap

a) 08-Jul-2009 to 20-Nov-2009 = Work related travel to India, but under UK payroll (135 days absence)
b) 21-Nov-2009 to 14-Feb-2010 = Work related travel to India extended. But payroll moved to India (85 days absence)
c) 14-Feb-2010 to 21-Mar-2010 = Travel UK to estabilish living in UK (35 days)
d) 21-Mar-2010 to 17-May-2010 = Unpaid vacation (57 days absence)

If UKBA treats my 135 days absence point (a) as 0 absence as I was under UK payroll and paying tax to HM revence. The rest of my absence are well below 90 days absence.

If my ILR application is presented with above justification to increase the likelihood, can anyone assist what types of supporting document might give a favourable result.
Also my absence during the Jan 2010 - Apr 2010 were also due to my wife's delivery. Whether my son's birth certificate and letter from hospital do justify my absence and ILR consideration?
