How to write Essays as an international student?

Hi!
I am an Au Pair from Germany and currently living in Colorado! After my stay I look forward to go to a College here. But to be honest I am kinda desperated with all the admission stuff and especially the essays! I already mailed one of the advisers for international students, but I have never received something back.
I don’t really know how to start and what the admission team except or if there is a specific structure I need to follow.
Maybe someone can help me out or send me helpful links. I hope you can understand that, the whole college system in Germany is very different and I have never sealed with that. Thanks!!!

Look up the common application - https://www.commonapp.org
That’s what most US schools use for their application.

In addition to writing the essay, you’ll need to have your high school transcripts and standardized test scores.

Be aware that there is little financial aid for international students.

Many colleges post sample essays of students they accepted on line. That will probably give you a good idea of what sort of things they are looking for. Academically you are likely to be better prepared than most US students if you’ve finished Gymnasium and have your Abitur.
