2. 2Photo with spectacles or grey backgroundMost portals insist on a recent colour photo with a plain white/light background and no spectacles or caps.
3. 3Paying the fee after the payment cutoffThe fee-payment window usually closes earlier than the final application date. Pay early — a submitted form without payment is rejected.
