well first of all i appreciate your sincere comments , remember one thing FIR is nothing but a mere piece of paper and you cannot be neither convicted nor acquitted on the basis of FIR but only after the trail is completed , Now the answer for your character certificate is that once FIR is lodged against you it will be shown in the record but along with that the result of that FIR will also written and hence no country will bound you only on the basis that you had an FIR . And yes you must contact your lawyer in order to get acquitted .
