The singer will release One & Two on March 12 as a nine-song collection in North America, marking her first new material in the territory for a decade.
"I love this new stuff I'm doing, and this feels more comfortable and more creative to me than anything I've done before," Church told Billboard.
The star is planning to perform a number of US shows next month, including an appearance at the SXSW festival in Texas, and hopes to do more dates in the future.
"I'd love to, but I wanted to come back out a little bit tentatively," she explained. "I'm not an egomaniac who's thinking I can just walk back into the scene.

"I've been gone awhile, so I want to see how it goes down and if people are interested and into it. If so, I'd love to give a great deal of my time and energy to performing all over America again, because I loved it the first time around.
"So I'm hopeful but... am being cautious about it."
Church's EPs One and Two were released in the UK last year and a third collection is expected to land later in 2013.
