No, this is not possible. Please read this post how applications are initially processed when they are mailed and received at the grant processing centre.same thats what they told me as well... Do you guys think it is possible some officer will take our apps to their desk...... then went on vacation and left all those apps behind until he/she came back...... somehow I have that feeling.. coz it doesnt make sense why other ppl's app which were delivered 2 weeks later got processed first...????

You are unnecessarily getting worried. Your application is not lost and neither it is gone into a black hole. Take some Valium for anxiety
