Would anyone know under what circumstances would someone with a valid Tier 2 General visa receive a call from Colnbrook Immigration Removal Centre ?
I have received a missed a call from this centre yesterday morning, but when I called them today, they said " we will call you when we want to".
Note: I entered the UK legally in 2010 as an MSc student, then got my PSW visa and then moved to Tier 2 general ( which is still valid until December 2016). I have never overstayed - and don't have any criminal record.
Anyone here had similar call/experience with this removal centre

Thanks,
