how eco makes verification of supporting documents ?

[gujjargujrati]

I am just curious to know that during eea fp process what kind of inquiries eco can make to verify that supporting documents are genuine ? he may call to employer and to the bank in uk ?
and why it takes so long in pakistan as compare to other countries ? do eco try to verify each and every supporting document for his satisfaction ?

Generally, if the evidence is not immediately clear they will refuse. Exceptionally, they may call an employer. They can't call the bank as a bank can't comment on the details of its customers. Things take longer in PK because of the volume of applications and the volume of fraud that emanates from that location.
