UCI for Canada visa

[vin18may]

Hi guys

I have scheduled my H1B stamping at ottawa on dec 18th.

Now I am in the process of applying for Canada TRV.

On the application form - they request UCI.

I had received a TRV in Nov 2011 and I believe i should have a UCI.

Is there a way to find the UCI from the old Canada TRV stamp on my passport ?

Based on my research - I see 2 numbers on the stamp.

1) B & 9 digit number on the right hand side printed Vertically (Red coloured)

2) B & 8 digit number on the left hand bottom printer horizontally

Can any of you confirm this ?

Thanks for your time
