Hi folks, 

I thought to post it here who ever is needing to recent immigrate to canada , normally Birth Marriage Certificate From From Pakistan Union Council is essential for such need . i was worried with the same aspect but a friend of mine in Pakistan recommended these guys (In highlighted links) to obtain following documents : 
English Marriage Translation Of Nikkah Nama duly attested by Notary Public And Foreign Affairs Pakistan 
English Birth Translation of your Birth Certificate duly attested by Notary And Foreign Affairs Pakistan 
Nadra Marriage Certificate of your Manual Nikkah Nama duly attested by Foreign Affairs Pakistan 
Nadra Birth Certificate of your manual old birth record or with the help of your cnic`s / nicop it is obtainable and duly attested by Forein Affairs Pakistan. any one can apply even if he / she is from UAE , CANADA , Saudi Arabia , Australia , United Kingdom etc. 

all these were accepted and either its Nadra Birth Certificate From Pakistan or Nadra Marriage Certificate From Pakistan just give it a try to these guys. at first i was worried with forge of documents took a chance and they couriered me the documents here. they were authentic and verified and also gladly accepted. it was worth. highly recommended to get in touch with them even if you may not have complete or any documents missing still they can sort it out for you.
