Tampa accepts walk-ins. I went today and they let me have it done. Took less than 10 mins.
Any idea how much time will it take now?? Canadian Immigration website is still stating 6 months...
Sorry, this is not an answer but rather a question - I too am trying to get the biometrics done at Tampa. The earliest appointment I received is of 2nd Oct. Did you get any update/ advise on if Tampa accepts walk-ins.
