She was originally expected to move stateside at the end of the October, but has been rushed over by Mr Trump, who personally approached her about joining the agency.
The Herald can reveal that the Miss Universe Ireland jetted off to Canada this morning to attend the exclusive In Style magazine bash at the Toronto Film Festival before she settles into her new career as an aspiring international model in the Big Apple.
Although she is no stranger to the runway, having carved out an impressive modelling career in Ireland over the past year, she will now be living it up with a handful of other models in the Trump Model Apartments.
Speaking to the Herald, Rozanna explained: "I can't wait to go, I only found out on Tuesday night that I'd be going so soon. But I'm always ready, it's what the job means.
"Since I'll be in New York, I'm going to meet up with Rima [Fakih, Miss USA], who lives nearby.
"I have no idea where exactly the apartment is yet though."
But the statuesque beauty said that she isn't intimidated by living in a house with a handful of other models, insisting the industry isn't as bitchy as everyone thinks.
And while she may be moving to New York now, she revealed that she will be moved around from various cities throughout the world for six weeks at a time in order to determine where her look would be most in demand.
"I don't know how many girls I'll be living with, it can vary from one to six.
"It's not as bitchy as everyone thinks, because we're not in direct competition with each other - we're all looking for different aspects of modelling.
"And you're never in the same place for very long. After six weeks, they'll see how that goes, then I'd go to London and Milan. They always try you in a different location to see how the client responds to you."
In spite of being tipped as the 'next big thing' to take on the international scene, she said that she is still the same old country girl from Clonmel.
"It's so strange, I don't feel different at all.
"Some of my friends treated me a little differently when I got back and I don't like that. But I pay no attention to any of the negative stuff."
In-demand Rozanna will also be acting as a guest judge at the Miss Venezuela pageant over the coming weeks.
