Will they be there?

My parents

For almost two months now I've been living with a knot in my stomach.
Everytime I think of my wedding (which happens a lot, obviously), I think about my parents being or not being able to come. They live in Russia, and their visit is dependant on them getting their entry visas to Canada. My FH and I wrote invitation letter, submitted all the docs regarding our upcoming wedding. It's been 2 weeks since my parents applied, and now, when decision time approaches, I think about it more than ever.
Last weekend we cleared and cleaned spare room in our house, it has an adjacent bathroom, my parents will love that. We are getting new bedroom furniture for them next month, and I want to make it comfortable when they come.
I know that positive thinking helps, and now more than ever I need it. They must be here! They will be here!

UPDATE: May 24, 2011
I found out yesterday that my parents' visa application was refused. They can't come for my wedding. I was devastated, my mom cried, I cried, my FH was utterly shocked at the news as well. My mom kept on saying how awful it is for her to miss a wedding of her eldest child, the first one in our immediate family.
We are now looking into webcasting our wedding ceremony and parts of the reception for my parents, and exploring the possibility for them to say a speech even if it's only via internet.
My friend who also applied got her visa, but I personally wasn't as excited. The entire day was marred. My FH and I would have done anything for at least one of the parents to be here.
