here the tricky thing ,,, if you done the test and got the DM ,, and if you done the test and you still IP ,, in the first case it is question of time with 90% guarantee that your file is approved ,, which means if you moved to other processing another they wont continue any treatment to you file ,, they will just sign you up in one ceremony session ,, also no one can guarantee that the transfer process itself it will be fast !!!
however if you still on IP ,, according to my understanding the Office still in process of treating your file and you will asking them at the top to transfer your file to other office ,, which my generate longer waiting time ,, same here my friend ,, I got sick and tired of waiting ,, I AM FED UP
