you got me confuse with your question...

if u mean visa cancellation, ur company just need to process thru e-government. bring the passport, printed receipt together with the iqama ID to immigration to stamp your visa in the passport with "cancelled" stamp & date. you have 7 days after the cancellation day to exit the country.

no other documents needed in immigration, unless you have an existing loan, some company require a clearance from the bank.
