@ousman you should contact both UTM and EMGS. In my case, UTM emailed the proof of payment to EMGS just after one or two days EMGS requested it and EMGS normally have to update one day after receiving the proof of payment.
Firsty do not wear white tshirt and shirt… and it must 35mm wide and 50 mm in length. Your head should fill 50-60% of the entire picture. There needs to be a 10 mm gap between the top of your head and the top of the picture. Same from chin to bottom of photo.
