I just want to express one thing. It is really medieval how NVC manages information.
I don't think it would be so hard for them to publish for each embassy, what was the last date of DQ they scheduled interview for that month. This is as easy as looking the last row of an excel table and bring all data in just one excel sheet for each embassy.
We would not have then this "Which DQ dates got the interview, which dates will get next month, hmm" syndrome.
NVC publishes how many visas are issued by each post every month for 2 months before. USCIS publishes how many cases are approved, denied and pending for each quarter. That is good things. But why not publishing how many cases are interviewed each month in each post, which DQ date was the cut off date etc.
I really do not think that would take more than 15 min for an employee to prepare. Everything there on their system already.
Just frustrated to check all the timelines, some of them partly filled, some of them filled with mistakes and try to make some assumption which dates are interviewed, which dates will be interviewed next batch etc. I wish NVC was more transparent on this issue.
