• 首先，您需要确定您的孩子想要申请美国高中的年级和类型。美国高中分为公立和私立，公立高中一般不收取学费，但是对国际学生有限制，只能读一年，并且不能选择学校。私立高中则可以根据学生的兴趣和特长选择合适的学校，但是需要支付较高的学费和生活费。美国高中有四个年级，分别是9年级到12年级，相当于国内的初三到高三。一般来说，最合适的时间是读初二时开始申请，初三时即9年级入读美国高中，这样就可以有完整的四年美国高中就读经历了，有利于今后申请美国大学。
• First, you need to determine the grade and type of US high school that your child wants to apply for. US high schools are divided into public and private. Public high schools generally do not charge tuition fees, but they have restrictions on international students, who can only study for one year and cannot choose schools. Private high schools can choose suitable schools according to the students’ interests and strengths, but they need to pay higher tuition and living expenses. US high schools have four grades, from 9th to 12th grade, equivalent to junior high school third grade to senior high school third grade in China. Generally speaking, the most suitable time is to start applying in the second year of junior high school and enter the 9th grade of US high school in the third year of junior high school, so that you can have a complete four-year US high school experience, which is conducive to applying for US universities in the future.

• 其次，您需要准备一些必要的申请材料和条件。这些包括：
• 护照：申请需要提交护照扫描件。
• 语言成绩：美国高中会要求国际学生提供英语标准化成绩，如：SLEP、TOEFL、IELTS或 SSAT等。不同的学校对语言成绩的要求不同，一般来说，托福最好80分以上，SSAT最好2250分以上。
• 成绩单：学生需要提供近三年的成绩单，并做中英文对照版，并在学校教育处盖章。成绩单主要是体现学生的学术水平和学习能力，好的平时成绩能证明学生是一个学习不错的学生。
• 推荐信：大部分学校要求学生提供三封推荐信，分别为英语老师、数学老师和班主任或校长。推荐信也是以评价学生的学术能力为主。如果学生之前就有在美国学习的经历，能请到美国的老师帮忙撰写推荐信是最好不过的了。
• 个人陈述：个人陈述可以让招生人员了解学生的个人情况和性格特点、以及学生为什么要转学。学生可以如实陈述自己想转学的原因，一般转学都是为了寻求更好的教育机会。但是在陈述转学原因时要加入一些目标学校的特点，并说明自己喜欢、需要这种特点，这样才能吸引到招生官的注意。美国的教育理念注重学生的全方面发展，学生的个人陈述还应该结合实际事例来表现学生的领导力和组织能力。如果学生做过一些对社会有意义的活动，也建议写进个人陈述里，因为这体现了学生有乐于奉献的精神。
• 家长陈述：有些学校还要求家长写一封家长陈述。家长陈述和个人陈述一样，也是要尽力展现学生是一个全方面发展的人才。
• 申请费：需要办一张能够网上支付的信用卡，支付不同学校的申请费。
• 财产证明：国际学生都需要提供财产证明，证明自己家有足够的资金支持在美国的学业以及生活支出。每个学校要求的存款数额不同，一般要求在50万元人民币以上。
• 补充材料：主要是针对有艺术/体育特长的学生，这些学生可以把自己的作品集、比赛视频等当作补充材料提交。学生还可以请自己的兴趣特长方面的教练、老师为自己撰写推荐信。
• Second, you need to prepare some necessary application materials and conditions. These include:
• Passport: You need to submit a scanned copy of your passport for the application.
• Language scores: US high schools will require international students to provide standardized English scores, such as: SLEP, TOEFL, IELTS or SSAT, etc. Different schools have different requirements for language scores. Generally speaking, TOEFL is best above 80 points, and SSAT is best above 2250 points
• Transcripts: Students need to provide transcripts for the past three years, and make a bilingual version, and stamp it at the school education office. Transcripts mainly reflect the student’s academic level and learning ability. Good usual grades can prove that the student is a good student
• Recommendation letters: Most schools require students to provide three recommendation letters, respectively from English teachers, math teachers and head teachers or principals. Recommendation letters are also mainly to evaluate the student’s academic ability. If the student has previous experience of studying in the United States, it would be best to ask American teachers to help write recommendation letters
• Personal statement: Personal statement can let the admissions staff understand the student’s personal situation and personality characteristics, as well as why the student wants to transfer. Students can truthfully state their reasons for wanting to transfer, usually because they want to seek better educational opportunities. But when stating the reasons for transferring, you should add some characteristics of the target school and explain why you like and need these characteristics, so as to attract the attention of the admissions officer. The American educational philosophy focuses on the all-round development of students. The student’s personal statement should also combine actual examples to show the student’s leadership and organizational skills.

• 最后，您需要完成申请和签证的流程。这些包括：
• 填写申请表格：不同的学校，其申请表格会有所不同，需要按照学校的要求填写完整和准确的信息。
• 提交申请材料：将准备好的申请材料按照学校的要求提交到指定的平台或邮箱，并在截止日期之前完成提交。
• 预约面试：有的高中要求申请者必须参加面试，面试需要自己去网上预约。在美国境内的学生如果方便可以选择去高中校园内参加面试。国内的学生可以通过Skype或者第三方面试公司进行远程面试。
• 等待录取结果：不同的学校会在不同的时间通知申请者录取结果，一般在1月到4月之间。如果被录取，学生需要在规定的时间内确认是否接受录取，并缴纳定金。
• 办理签证：拿到美国高中录取通知书和 I-20 表后，可以申请F-1签证。持F-1签证的国际学生在美国的公立高中只能学习一年，一年之得转学去私立高中。办理签证需要准备好相关的材料，并预约签证面试。
• 行前准备：办理好签证后，就可以开始准备出行了。这包括购买机票、保险、行李、衣物、文件等等。还需要了解目标学校和城市的基本情况，以及美国的文化和习惯，做好心理和身体上的调整。
• Finally, you need to complete the application and visa process. These include:
• Fill out the application form: Different schools have different application forms, and you need to fill out complete and accurate information according to the school’s requirements.
• Submit application materials: Submit the prepared application materials to the designated platform or email according to the school’s requirements, and complete the submission before the deadline.
• Schedule an interview: Some high schools require applicants to participate in an interview, and the interview needs to be scheduled online by themselves. Students in the United States can choose to go to the high school campus for an interview if convenient. Students in China can conduct remote interviews through Skype or a third-party interview company.
• Wait for admission results: Different schools will notify applicants of admission results at different times, usually between January and April. If admitted, students need to confirm whether to accept the admission within the specified time and pay a deposit.
• Apply for a visa: After receiving the US high school admission notice and I-20 form, you can apply for an F-1 visa. International students holding an F-1 visa can only study in a public high school in the United States for one year, and must transfer to a private high school after one year. Applying for a visa requires preparing relevant materials and scheduling a visa interview.
• Pre-departure preparation: After obtaining the visa, you can start preparing for the trip. This includes buying tickets, insurance, luggage, clothing, documents, etc. You also need to understand the basic situation of the target school and city, as well as the culture and habits of the United States, and make psychological and physical adjustments.
