I have been following the posts for a while now, you guys are going a great job.
Here is my situation...
I have got an HSMP approval last month (applied from within uk). Unfortunately before I could apply for Leave to Remain my stay expired and I am now leaving for home to apply for EC

What documents do we need to apply for EC?
1- Where do I download the EC form from and what form do I download.
2- I am employed in UK and all my statements, payslips etc are UK based, can I show these in my country of origin?
3- Do I need to provide anything else apart from Application form, bank statements, salary slips and letter from employer?
4- and pictures
5- Do you guys know roughly how long it takes to get an EC approval.
My biggest concern: I have overstayed in uk (just by 4 days) would its effect the EC decision.
Thanks all in advance & regards,
