Why are you asking here you do what you want try asking the embassy. Sounds like you didnt research in here prior to you application do you documents are all over the place. You need to give the embassy what the application requires no more no less. You obviously haven't supplied the correct documents originally or the first or second time as requested. Its pretty simple you will get a specific request as show here by previous applications that have been requested more documents. You never did this just typed in what you think they are asking for. You must be specific if you don't know contact the embassy. Don't give them just stuff. You booked the accomodation and flights again if you did your research the advise is not to until the dtv is issued. Stop whining give the embassy the correct documents and you will be approved. Or go to another embassy but it sounds like you will try shortcuts wherever you go.
