hey guys,
im a Chinese and my husband is a Canadian citizen.
in 2011 i applied for and got 2 TRVs, one was single entry and the other was multi-entry. and i visited Canada 3 tiems in 2011 and 2012.
in early Jan 2013, i submitted my spousal sponsorshuip immigration application. in the form IMM0008, i didnt write anything under the item of UCI because i thoguht i don;t have one.
but today i heard that anyone dealing with CIC would have a UCI. so i guess maybe a visitor visa (RRV) also have a UCI?
i checked the two visas on my passport and found on each of them there was a 8-digit number string started with "88".
is that my UCI?
if yes, what would happen if i forgot to write my UCI on IMM0008?
thanks a lot!
