I don’t believe this is true. If you check the Imm Tracker you will see India and China applicants being approved last week.I have the same status . Since have used a rep, I quizzed them about this. Here is what they had to say.
"We just attended a professional seminar on immigration and we received the latest updates. Many quotas are reached for the year and they will not be issuing more visas in those categories."
These are unofficial quotas however country quotas have got over for the larger contribution countries like China and India. Hence the possibility that they will not start security till Jan 19(when the new quotas come online) is large.
