I remember one case where it got approved after submitting BRM letter in lieu of client letter. It may work in similar way in your case, but it is officer’s discretion.
Can you please let me know what job title you have put in End client letter and organisation chart. Is it same as what you put in PRD document ?
Please mail me @ "rajeevujain@gmail.com".
My case is same as yours.I am also not able to give end-client letter,so I also need to give BRM letter.Have you got any response after submitting your RFE docs?I need a sample of BRM letter.Can you send it to mou.pinki@gmail.com
