Hi Mohsen77You have to pay additional fees and send the required documents along with a cover letter to the ministry.
I am really thankful of your reply and please let me know what documents I have to submit as a work experience. Can I just submit appointment and experience letter as a work proof. or I have to give any other info as well like salary slips for all the months, appraisal letter etc. It will be really appreciated if you can provide any experience letter format. Sorry for so many question actually i can not afford immigration consultancy fees so want to file my self so just want to clear my all doubts to avoid any mistake. Looking forward to hear back from you. Thanks
