One of my friend has asked for a Declaration Letter for his parents. He is applying for his parents on compassionate grounds. Is it okay to give a Declaration letter along with my details (Passport Copies). He has some old pictures of us with his parents and he plans to attach those as well. I have never given any such letters before so was wondering if its okay to give such a letter. As I will be trying for my parents in the future and don't want it to effect my case negatively. Thank you for your help.
