ILR for dependant

[T1ilr]

Hello again,

A while ago I had discussed about my personal circumstances and whether my missus should go to home country for delivery. Many seniors had suggested pros and cons. At last, we decided to deliver in our country due to family n friends ties and the help she would get. My wife's visa timelines are:

Arrived uk 15th June 2012 as tier 1 dependant
Visa valid till 26/01/2014
Left uk on 3rd July 2013 for delivery
Planning to return April 2014.

Could someone suggest when she'd qualify for her ILR please?

As she is in 2 years route, can she apply in June 2014 or since she was away, does she has to compensate for the lost period as well.

Many thanks in advance,

Kind regards
