My wife came from Pakistan in 2016 on the 5 yr route, we applied for her first leave to remain in 2018, but it got rejected because it got there 1 day late. They sent the below statement but:
* At what point does she apply for indefinite? 10 years from 2016, 2018 or 2020

* Do I still apply as a normal spouse partner application, or parent?
* Will the A2 test she did be applicable as it isn't classed as continuous, therefore is it best if she does B1 now, and use that for all future applications?
Letter 30 April 2018:
You applied for leave to remain on 30 April 2018 under the Appendix FM 5-year partner route.
However we have decided that you meet the requirements of the 10 year partner route under paragraphs R-LTRP.1.1.(a), (b), and (d) of Appendix FM, as you have a parental relationship with your British child, and it would not be reasonable to expect them to leave the UK.
Accordingly you have been granted a period of 30 months limited leave to remain on the 10 year partner route under paragraph D-LTRP.1.2 of Appendix FM.
We have decided that you do not meet the requirements for a grant of leave under the 5-year partner route under paragraphs R-LTRP.1.1.(a), (b) and (c) for the following reasons:
It is noted that your precious leave as a Spouse/Partner ended on 29 April 2019. You have therefore been without valid leave in the UK for 1 day and paragraph 39E does not apply. You therefore fail to fulfil E-LTRP.2.2 of Appendix FM of the immigration rules.
Then a statement about no recourse to public funds etc.
