Guys,
I had biometrics appmt at Newark,NJ on April-28. Did an early FP at Woodside ASC center NY. We (myself and my wife) went to Varick ASC NY first, but they sent us back saying, "Early FP can be done only on Wednesday".
Per plan, took train to Woodside (Jackson Heights) ASC, NY same day.
There was long line on the street (~40 people) near the ASC. It took us about 2hrs to get in and have our biometrics done. No questions were asked on early visit or visiting different center. Try it on Tuesday or Wednesday.
Good luck!
