* Equivalency: The college will need to determine if the foreign high school diploma is equivalent to a US high school diploma (or the equivalent in the country where the college is located). This often involves submitting transcripts and possibly having them evaluated by a credential evaluation service. The evaluation service assesses the foreign education system and determines how it compares to the local system.
* Specific College Requirements: Each college has its own admission requirements. Some might be more lenient than others regarding international credentials. You MUST check the admission requirements of the specific city college you are interested in attending. Their website will have this information.
* Language Proficiency: If the instruction at the college is not in the language of your high school diploma, you may need to demonstrate English (or other relevant language) proficiency through standardized tests like TOEFL or IELTS.
* Documentation: Be prepared to provide not just your diploma, but also official transcripts, a detailed course description, and potentially other supporting documentation as required by the college and/or evaluation service.
In short, while it's *possible*, it's not *automatic*. You need to contact the admissions office of each city college you are considering to find out their specific requirements for international applicants.
