You can't by default take a "gap year" in the middle of your course, you need to see if your uni permits that for your stated reason. Normally interruptions of study are for people who have health issues or other extenuating circumstances (bereavements, visa issues, etc), or sometimes unis permit them for students who already have a yearlong full time internships/work experience opportunity lined up.
Just look for other internships or work opportunities over the summer, especially at smaller organisations or regional offices of larger ones. There are internships outside of the global headquarters of major multinational corporations.
