I got the hsmp approval after 3 months from the date of the approval. I dont know the reason, I think its postal delay.what is the process for extension..what will be the fees, where I have to send the application..

i suggest you to send your questions to wpcustomers@ind.homeoffice.gsi.gov.uk email adress, someone will answer your question a few days later. i tried it once, it works.
btw, HSMP application verification procedure requires "orignal certificates", how do u handle that? I am also thinking of applying HSMP, but i hesitate a little bit when i saw this rule. i have never sent my original cerficates by post since its importance, i know once it is lost, i am not able to recover them. pls advise. thanks.
