The well-known lingerie model, who has been working in America for the past five years, feared a Mitt Romney victory would make have made life unbearable for the Irish Diaspora.
And Roz is keeping her fingers crossed that Obama will be able to provide better working conditions for the millions of Irish making a living Stateside.
She told the Diary that she had to come back to Dublin a month ago to sit out the lengthy process of having her working visa renewed by her modelling agency as they wade through all the red tape.
"Hopefully he'll make it easier for the Irish over there in terms of the visas, as that's why I had to come home for a few months," she explained.
"I'm delighted about him getting in, first because of his Irish roots and the fact that he has links to Moneygall.
"It's fantastic for the Irish to have that link, as he's done a lot for us in terms of tourism and everything else.
"I did stay up and watch it and I know a lot of Irish-Americans were down in the Guinness brewery watching it live and there was apparently a brilliant atmosphere.
"I think people are really delighted with him winning a second term."
The brunette model said she has no definite date for returning to America and will be spending Christmas with friends and family.
On coming home last month, she jumped ship from Assets agency to sign up with Andrea Roche and said she's been inundated with work ever since.
"I've been doing a lot of fashion shows, working this week with Arnotts and in Brown Thomas, so it's all going great.
"It's great to be kept so busy," she continued.
Now signed with Wilhelmina model agency and Paradigm Talent agency in Los Angeles, she has also turned her attentions to making a name for herself as an actress after putting her legal studies on hold for now.
She was previously based in New York before deciding to head to California for a stab at stardom.
She's since kept herself busy making contacts and taking acting lessons.
"I'm living in West Hollywood in LA, which is so central, and the pilot season is coming up in February.
"I'm grateful to have modelling as a vehicle to explore other avenues," she added.
