I think you should relax....you are going through the normal process....I you are in queue for review it's about your eligibility check and everyone has to go through that. I think you should read this so you understand the mess and what's happening right now....Yeah it’s helps and makes a lot of sense …well after I paid the biometrics fee they instructed me I did my police clearance then after they sent another mail to do my medicals ..then I saw it in my online tool account that medical results received …and it’s been three months now …heard nothing since then does mean I passed my medicals? ..being trying to link my Gckey account but it doesn’t work ..I emailed Accra visa office since I knew now my application was there and was told my application is still in a queue for review ..what does that also mean ..is it good news or more delays ..assist your brother with this info wai..I’m a Ghana man and you know we can’t be too away from our wives ..lol..
