Mr. Usman Awan- it seems like you've included a LOT of information, so i'm not positive what they could want. but it's possible (since they said "background information") you need to add even more details. for example: list EVERY school you ever went to and list at least 5 previous jobs. unless you're referring to a "background check", because that is something totally different : )

thanxx odette. i have explained my work and experience and also biography.i also write about my work experience in biography , so about which option you are saying ? about work and experience or about biography because just these 2 are options to explain about yourself

you should tell them more about your personal information...
