As someone who has been responsible for soliciting resumes for internships, let me assure you that patience is important. I know it can be frustrating not to hear back quickly, but many employers are inundated with resumes and are unable to confirm receipt or follow-up with everyone. However, I've experienced tons of people calling and emailing checking in to make sure and ask about the process. This never helped applicants since I could could get dozens of unsolicited calls and email message each week of a intern search.
As a general strategy, you can increase your odds of getting an internship by reaching out to people at the company before an internship opportunity is offered. To do this, you can try to track down people at the company who went to your high school or lived in your town. Many people share that information publicly, so it is not necessarily that hard to find. Once you find the right person, reach out via email or telephone to introduce yourself and ask a question or two about the company. Many people are happy to help when all you are asking for is basic information Then, when an internship is available later, you have a friendly person you can contact to ask about your status in an internship process.
