My wife was granted a PBS dependent (I was on Tier 1 General) visa in 2015 for a year and we later extended that which now expires in 2019 (she was granted an extension for 3 years)
By 2019 she would have completed four years. She needs another extension but I have two questions
1. When we apply for an extension now how many years would she be granted a visa for? Would it be only a further one year so as to allow her to complete 5 years and apply for an ILR?
2. How soon can we apply for this extension? Her visa expires in Feb 2019 should we wait till Jan 2019 or can we do it much earlier i.e. at some point towards the end of this year?
