Sorry admin, I know this is not the right thread/ space for such kind of posts, just trying to help..
Rameez Raja - I am not sure about the documents evaluation for employment purposes but for CPA I got my credentials assessed through WES.. their process is straight forward, go through their website and you will know what to do.. If I remember correctly you would need to create an account with WES, provide information that which school you will need your degrees assessed for (CPA WSB) and pay the fees after entering all of your education hitory, once done you will get some sort of a form/ paper that will have WES address and information on how to send you attested degrees to them.. send this to your family in Pakistan who will take this to HEC along with your original degrees/ certificates, HEC then, will attest and give him the sealed envelop which he will mail to WES directly.. But remember HEC will only attest your degrees if you have all of your degrees and certificates attested from univesities and schools first so before going to HEC your brother will need to get your secondary and post secondary certificates attested from relevant boards (Rawalpindi Board/ Punjab Board etc) and degrees I am sure are already attested from universities in Pakistan but double check to make sure... One WES jas received your degrees, they will send them to CPA who has their own process of assessment, one thing I forgot to tell you that before this whole process you will need to apply for admission in CPA and CPA will then ask you to get your degrees assessed and sent to the, they have their own fees for this...
Hope it helps
