Desperately in need of advice and suggestions for my resume!

Add GPA and Relevant courses? Put the skills and interests category at the bottom, and take out certification. Imho citizenship is not really that interesting when you're trying to work in the U.S.

Overall, the format looks good. Is there a reason you don’t have your GPA listed? I assume it’s terrible if it’s not listed. Also, if you have good SAT scores, I would list those as well. Since you’re a student, your biggest accomplishments are likely related to school. Were you involved with any clubs at school? You don’t need languages under your interests, you already mention that you are fluent in French and Spanish, so it’s implied. Do you have any metrics you can use for the jobs you have?

Put skills & interests at the bottom, remove languages from interests, and I personally would remove citizenship.

You got an empty line between job title and ur first bullet in ur 3 jobs, but not in the last one. I'd be consistent, but maybe Im just OCD
