Show “interest” (see below) at Dickinson and Grinnell.
Dickinson is excellent for international relations and study abroad.
(Note: try to reach the highest level foreign language your school offers.)
Grinnell is in Iowa and highly selective, probably quite different from what you know, huge resources to support each student’s goal.
If you give your top LOR recommender a “brag sheet”, it’ll be easier for them to say yes. In it you summarize your grades etc, but most importantly, 3 super important things you learned in their class in terms of content (1), of skills (2), and personally (3); what lesson or chapter struck you and why; what you loved in that class; a chapter or unit or text or cartoon or film or… that blew your mind and why… Then, examples of what you do outside of class but at school that relates to the subject(s), whether you’re known at school for doing X, Y or Z…
To show interest (important at all private colleges): create a college email (name.number.college at mailsystemofyouchoice .com), look up “join our mailing list” for each college listed on this thread, check it regularly (several times a week), open all messages, click on links that sound interesting. You don’t have to click on everything 
but not opening the email or not clicking, v. clicking and what, is tracked as an example of genuine interest you have for the college.
