35 days left before heading to America But that is not a complete sentence. Instead, you might say: There are 35 days left before/until I head to America.

Hello Lina: Mojave gives a good answer. I would suggest also, that rather than emply a colloquialism, like "head to," that you simply use the word "go" and the phrase "before I go to America"? Trying to use a vague colloquialism can lead to difficulty. For example, you might think that you can use "head to" in a different situation, and write something very awkward. Clear communication begins with the employment of simple vocabulary. "Go to" is something that all will understand. .
