So this is the reason they gave of refusal :


We have provided all the chat records between my parents and the recipet for the money my dad sent every month .... Marriage certificate and all the proof i could , i did not think pictures would be required because of the length of the marriage.
Now i am sending all the pictures from the marriage to after their life and pictures of my dads recent visit with my mom.
My sister is disable and she cant talk or take care of her self and her visa was refused on the grounds of that we did not proof that she is my dads daughter which is so stupid , we provided the birth certificate , we lost her original birth cetificate in a fire long time ago so we got issued a new one for her and they said because it was a duplicate and they said it might be faked they rejected her visa as well .. Feels like they are nit picking little things with no merit ..
So guys any advice because we have a right to appeal and we are going to appeal but what are the chances of us winning .... the reason of refusal are so silly , i feel like they just want to make money and that is the only thing they care about ....
