According to your analysis, number 3 is the most possible, that is 7/2日递入的人凭借退件收据可以在排期到后保持当前的交费标准递485。Is that every one fight for? Just like what I said this may be this is the thing people concern the most. I hope every one can get compensation on money they lost.
Again, 递485 this time may not be a good thing, because no visa number left. This is not likely to change any soon. All 485 will stack in CIS, which is not a good thing too applicants too.
