Thanks for your advice JimmyBoy ....What you have mentioned about one year of stay before I left, did not seem to be on the rule book when I applied.Do not get me wrong, I may have missed it.But it would be helpful if you can point out that rule for me.Thanks.
Its not easy. When i submitted at passport office i only needed passport copy and application form but after 2 weeks your local police department will contact you for inquiry and address verification. They asked me for lot of documents like birth certi, scholl leaving certi, driving licence, latest light bill, visa copy of all country u visited, police clearance from all coutryies u stayed for more than 6 months and many more.
