Hey there!

You can apply to the colleges you want to enroll in United states. Generally they ask for your SAT scores and maybe some other examinations like TOEFL and AILETS. These are all globally recognised examinations and can be used to get admission in Universities around the globe. Other than that you'll need a letter of recommendation as a strong profile to get admission in the top colleges. Start by preparing for the SATs and looking for universities you'd like to enroll in.
