Hi Sadika,
I think at the level you are now, you should not be contemplating on re-applying. You already paid RPRF and you want to withdraw your application. Note that no refund will be granted as processing had started on your pre June 26 application.
Secondly how are you so sure that everything regarding the new application will just be fine? Think of the documentation, the time and energy.
I have two applications running, one post Feb 2008 and pre June 26. My ecas is saying RVBO. Before now, priority is given to us pre June 26, but bcos they changed the rule, its seems we are not under priority anymore. What gave you assurance that as soon as you apply in April 2011, and keeping in mind that there is going to be a change of rule in July that there won't be delay yet again.
You have paid the last fee expecting your PPR and talking of applying new!
