Schengen Visa for germany Refused due Reason #8. Should I Appeal or wait to reapply after 3 months
I am Pakistani working as Assistant Manager in Abu Dhabi. I have applied for Schengen Visa for Germany in Abu Dhabi on 06/09/2015 for 10 days and I was called for an interview on 16/09/2015 and after the interview the Embassy Refused my application on 22/09/2015 giving reason #8
It was mentioned in German Language (Die vorgelegten informationen uber den zweck und die bedingungen des beabsichtigten Aufenthalts waren nicht glaubhaft) and also in English (the embassy does not hold that you have convinced it that you are going to Germnay for the purpose stated in your application)
Now What is the process, what should I do in this case. Is it good to wait for three months and reapply or it will be better to appeal.
