I want to say thank you first for helping I got advices to call immigration and talk to tier2 si he should be able to give me more information. I did it and luckily I got the day he even sent a copy of my interview letter by email it’s February 27.

Now I need some advices I was married before and divorced they called us 2 times for interview we never go because my husband and didn’t get along I didn’t want to continue because he was cheating I got all the proof it was too much I told my lawyer that I wanted to divorce . I was married the firt time on October 2016

First interview was in november 2017 we didn’t go because he was in jail and get out a couple days before we wasn’t ready and I wasn’t sur to continue this marriage
