Continuous stay breach for ILR

[monushh]

Dear Expers

I am on Tier-2 General visa, so do my wife and my child (as dependents).

My wife and my child are planning to stay overseas for a couple of months.

My wife is planning to stay for 6 months and my child for up to 1 year.

Therefore, I would like to seek advice on the rules for the maximum stay for dependents under this category, so that we will be eligible to apply for Indefinite Leave to Remain (ILR).

We would like to seek information on the following points relating to the same:

1) I am the main applicant and I will make sure that I am not overstaying the restricted stay of 180 days in continuous 5 years stay for ILR eligibility.

2)I will be the main applicant for our future ILR appication, therefore will my dependents have the same rules as that of mine for ILR application?

3) How many days maximum we can stay overseas in a 12 month duration without breaching ILR conditions?

Your advice on this would be deeply appreciated!

I will look forward to hearing from you in due course.

Many thanks.
