How to Stamp Suadi Business Visit Visa in Pakistan

I got Business Visit Visa for my Sister and Brother through one of the Agent.

He told me that to stamp this Visa in Pakistan requires Company Employment Letter.

I didn't get full Information before getting the Visa, Now i don't know what is the Procedure to Stamp this Visa from Saudi Embassy in Pakistan.

Mr. Wasim Ghazi,

Your agent is right. Your sister and her husband can come to Saudi on a business visit visa as long as they could prove that they are in a business in Pakistan.

Following are the documents which will be required by the Saudi Embassy.

a) Income tax returns for the past 2 years.

b) Bank statements for the last 6 months showing healthy transactions.

c) Membership and letter of recommendation of Chamber of Commerce.

d) Proof that applicant is a proprietor or a director if the organisation is a private limited company.

e) Letter of invitation from the Saudi company in the name of Pakistani firm.

I hope this information is helpful. :)

I don't have any of above  :(

any other way?
