The songstress received approval for her petition for a three-year entertainment visa last week and will meet with the US Consulate on Thursday.

“They go through my case and confirm that everything I’m saying is correct. Then they’ll take my passport, and put a sticker on my visa,” she said.

Katrina was set to fly out on September 7 but had to put her flights on hold when her visa didn’t come through.

Katrina said she decided that she would stay in Australia until early January, with plans to gig in the local area in the coming months.

“I really do believe that everything happens the way it’s meant to happen and I just surrendered to it,” she said.

“I normally have a lot of gigs in summer. I can get like five gigs in one week.”

Katrina said the wait had been “really challenging” because she had been “knuckling down” and was ready for the next big thing.

“I was prepped and ready to go for the last month and a half, so I’ve been sitting around twiddling my thumbs which is hard when I’ve been running full steam for two years,” she said.

“I really do need a purpose in my life at all times, otherwise I just crumble, so when you’re sitting in limbo it’s so difficult and challenging.

“I’ve got this journey that I’ve got to go on.”

The 28-year-old will arrive in America mid-winter and said she is gearing up for the cold change.

“I’m definitely going to enjoy my last Australian summer,” she said.

Despite the months ahead before she’s settled in Nashville, Katrina said she looked forward to having a place to call home after living out of a suitcase for a year.

“The funny thing is that most of my life I’ve never invested in furniture because I’ve always thought I’m going overseas so it will actually be nice to have my own place and my own furniture. And I’m actually excited about that,” she said.

“This whole experience is just like moving out of home for the first time. I’ve got to go over there and buy a cheap little car and try and make ends meet until I secure an income.

“I’ve got a little family over there and people I can rely on, so even when I’m lonely, I know I’ll be okay.

“I call them my Nashville family. They’re people I love and adore and I trust them 100 per cent.”

Katrina said it took nine years to build her own business in Australia and she would have to start all over again in Nashville.

“Instead of playing pub gigs, I’ll have the opportunity to focus on being a published writer,” she said.

“I can sort of go over there and do what I really love and do what I’ve been working to do.”
