you will never know, it's been only 9 months and they already had different reactions every a few months from the embassies side and the immigration side in the airports as well
i can advise one thing , i already have my DTV but before i apply i sent an e mail to the embassy asking about all the requirements and the documents they need to apply for DTV, and i made it very clear i want to receive full details so i can prepare it before i apply, the next day the embassy send me everything they need after that i applied and approved without even interview, just an advise so you don't lose more money for nothing
i think this is a hidden message from the embassy !! they don't want any tourists to apply for DTV spically after all those people abusing the the visa !!
