I have got my ILR in Apr 2019 and my spouse and child are in tier 2 general dependent visa till 2020 May.
They will be eligible for ILR only by 2020 June (short of less than a month time for ILR)
Have couple of queries
1)Can we all travel outside of UK with their Tier 2 gen dependent visas or do they both need to apply and be my ILR dependent? We have our tickets done for October, we assumed it was ok to travel

2)If the answer is yes to the above question; when can they apply for an extension of their current PBS dependent? Is it possible to apply as early as February?
3)If the answer is No to the 1st question; which visa should we apply for them?
(You guys had really helped me in the run up to my ILR; many thanks for the same again

Thanks & Regards
