Welcome to tFS, spectre! 
 
Internships in the US are usually not paid. You are probably seeking an entry level job.
 
I'm going off topic (internships) for just a moment to direct you to some of the appropriate threads about fashion jobs and careers and related info ... then off you go into this exciting forum about careers.
 
Now is the time for you to look into a work visa if you have not done so already, if you intend to do paid work in the U.S. It's complex and a challenge for most ... so you'll need time to work on that. Here's a link the the
 U.S. Citezenship & Immigartion Services ... where you can learn more about being allowed to work in the U.S. ... either permantley or as a student ... there are links to various types of authorization ... a bit convoluted to find every thing you'll need to know, but then, that's kind of how our gov't usually is.
 
We have a thread in this forum (Careers & Education), pinned at the top for networking for people in fashion, but it rarely lists real paid jobs (mostly internships), but keep an eye on it when you are ready to make a serious move.
 
If you are interested in the various types of careers you might find in fashion ... there's a thread about 
finding the right fashion career, which can start you off. Then ... most of those careers have a thread ... use the advanced search (
thread about how to do that here) to find each one to learn more about the particulars. And there's a small thread about 
fashion websites ... which list career opportunities. Not everything is in the U.S. ... since we have members from all over the world here at tFS.
 
Hope this gets you started on your research.
