H1B extension successful ....Stamping in canada/ mexico etc Possibility

Hi Team,

My H1B Visa is successfully extended for next 3 years.
I planned to visit Bahmas ; unfortunately that division requires stamped visa on my passport.
My Visa expired in Sept 2014 and the extension is now successful.

I hear from couple of my friends that earlier poeple use to visist canada / Mexico / Jamica etc and get their visa stamped in the passport.

Could you please let me know if the same facility is still available. I am new to US and hardly spent a year here.
Look forward to some advice. Thanks.
