comment The limit of integer valued random variables must be integer valued?
OK. BTW, does my example shows that the portmanteau theorem works only for random variables on $\mathbb R$?

comment The limit of integer valued random variables must be integer valued?
It's not clear whether the author meant to define $D_n$ and $D$ in $\mathbb R$ or compactification of $\mathbb R$. That's a question that comes to me again and again -- When the author says "random variables", does he/she allow them to take $\infty$ as value or not?

comment The limit of integer valued random variables must be integer valued?
Thanks. I'm actually aware of this theorem and it is how I thought I had proved it. But when I came up with the "counter example" that I got confused again. Can we say that $\infty \in \mathbb Z$?
