Taylor, who went public with her romance with Harry, 18, in early December, is worried their whirlwind romance won't work if he is living in the UK.
An insider tells us: "Taylor has fallen for Harry big time but she's realistic enough to know they may not last if it's a long distance relationship.
"She keeps telling Harry she can't bear being apart from him, and he's so smitten with her that he's already started looking at ways to make moving to America work."
Harry - a well-known ladies' man - was linked to Taylor earlier this year until she saw pictures of him kissing a model while 1D were on tour in Australia.
And recently, Harry was pictured posing with a bunch of pretty girls at a friend's house party so it's no real surprise that Taylor is starting to fret that he may stray again.
