We cant simply trust lawyers for anything as they are just to take the money. But surely 2 years is good enough period to give it a try but i dont think one should try it within 2 years(its waste of time and money as cic has easy excuse of covid, lockdown, online test launch delay etc).
I was thinking that i would wait till the standard processing time to think on legal filing but they are still stuck at early to now mid 2019(June 2 and 8, 2019)

Seems it would take more than 1 year from now to reach Feb2020
