Hi Tamimbd,
I actually applied online bro so can't tell for sure how VAC was like. However, I submitted my biometrics there and they seemed pretty cool and fast with the whole process. And then after that I had nothing to do with them. However, after passport request I visited them yesterday and submitted it. They didn't ask me anything since I completed my application online but only gave me a rough estimate of when I should be expecting my passport back. She said the max would be within ten days. I think that's an exaggeration as I have seen people receive their passport back within few days but can't tell for sure. She gave me the tracking number with the receipt and asked me to visit their website to track the passport movement. Lastly, she said that I should be expecting to see an email when the SG office receives my passport and also when they dispatch it. So now I have crossed my fingers
