Sorry for the late reply
@MB1xxx. I was not able to use my mobile internet.
My visa status is now changed to 'Issued' after many fluctuations between 'ready' and 'administrative processing'. I'm waiting for an email from DHL as my passport gets ready to pick up.
In addition to my status, i also got case number of a family (by random check). As I followed their case, I found out that only the status of the principal applicant had been fluctuating. The others were ready all the time. Finally, the status of all member had gone to 'administrative processing' for two days and then all went to 'issued'.
I think you well observed the scenario. So, you can expecte your visa to be printed when the status of all members come to 'administrative processing'. Then it will be changed to 'issued' once the visas get printed.
