As previous topic has been locked, I can not update the information on that post.
So I post a new one.
I already contacted UKVI several times. They always said my visa is still not yet been completed.
I do not know why it tooks so long. The checklist requires the the application form, passport, old brp,photos and police registration. The documents are not too much to consider such long time. By the way, the main applicants got the ILR this march.
I am so appreciate that anyone can provide a suggestion. Or is there any people got the same situation? So far, I heard two people they has been waited around 10 months.
