Thank you so much again!!! I am so happy, now I have to pack, pick up the kitty and move to my husband to live long and happily

Nothing changed in my English language, so even taking the risk of using the same IELTS for UKVI test certificate, we were approved.
For everyone, who had rejections previously, I would still recommend re-applying, instead of appealing, if you can afford it. The rejection really hurts emotionally and financially, but time together is much more precious.
I will travel to the UK in the mid-May. My husband is coming next weekend, so it would be useless traveling for me and will create more troubles with documents, taking into account the fact that i can't pick up my BRP earlier than 8th of May.
