Application and Acceptance

Holy Trinity works with each international student throughout the application process to ensure that the proper documents are submitted for obtaining an I-20 and F-1 Visa. International students must first be accepted to Holy Trinity and then must obtain the proper visas required by their country to study in the United States. We work with a variety of agencies and individuals to help international students enroll at Holy Trinity High School. Initial required documents include:

  • Transcripts/academic records
  • Key to grading system
  • TOEFL/ELTiS scores
  • Student birth certificate
  • Passport
  • Bank statement/letter, not more than three months old
  • Current medical records: physical examination and immunization records

In addition, students will be asked to interview by phone, by video chat, or in person prior to acceptance.

Note: Holy Trinity does not provide or arrange for home stays. International students should work with an outside agency to arrange housing with an adult guardian, as required by the Office of Catholic Schools, the issuer of I-20s.


The 2024-2025 tuition for international students is $12,300 plus approximately $600 in books, fees, and uniforms.

  • Each student is responsible for purchasing his or her own books, dress code approved clothing, and cafeteria items.
  • Tuition paid by in full before the start of school will receive a $250 discount.



Holy Trinity High School accepts transfer students at all grade levels at the beginning of each school year and at the start of second semester.  Students interested in transferring to Holy Trinity do not need to take an entrance exam.

To apply, submit all completed admission forms and documents to the Director of Admissions.
