由於網友非常好奇「赴美交換學生」的資格，因此直接寄信給美國國務院負責「交換訪客計劃」（Exchange Visitor Program）的單位詢問，並獲得對方回覆說明，該計劃是讓「外國國民」赴美進行教育及文化交流；至於「中學生計劃」（Secondary School Student Program）則是讓外國中學生前往美國就讀，但申請學生必須由美國國務院指定的贊助方接受、取得DS-2019表格後，再在自己的國家申請J-1簽證。
由於該次回覆中並無直接回答「學生若具有美國公民身分是否仍符合參與資格」，因此網友再次回信追問。PO文曝光後隨即引起熱議，不少網友都相當好奇後續：「留個言卡後續，殷瑋為了救主爆料這屆有3、4個美國人，看會不會全滅」、「我更想知道如果真的違規，美國會不會取消他的綠卡」、「美國不允許有美國護照的公民持其他國家護照入境，他如果去申請簽證就會會被查到了，光這部分就不符合美國方面的資格了吧？」
以下美國國務院回信全文：
Thank you for your inquiry. You have reached the Office of Private Sector Exchange within the U.S. Department of State’s Bureau of Educational and Cultural Affairs （ECA）. This office administers the Exchange Visitor Program, which is overseen by the Deputy Assistant Secretary （DAS） for Private Sector Exchange in ECA. The Exchange Visitor Program is for foreign nationals who come to the United States for international educational and cultural exchange experiences.
The Secondary School Student Program is part of the Department of State’s Exchange Visitor Program. The program is designed to give foreign secondary school students the opportunity to complete up to one year of academic study at an accredited public or private secondary school in the United States. In addition, these students are given the opportunity to live with an American host family and participate directly in the home life of the family. Some students may also attend and reside at accredited U.S. boarding schools. Students attend school as full time students and may attend for not less than one academic semester （or its quarter equivalent） or more than a full academic year.
Eligible foreign participants must be between the age of 15 and 18-and-a-half years by the first day of school or have not completed more than 11 years of primary and secondary school education excluding kindergarten. Students who have previously participated in an exchange program utilizing the J-1 or F-1 student visa may not participate. Students may not be placed in the homes of relatives.
To participate in the Secondary School Student Exchange Visitor Program, students must be sponsored by one of the Department of State's designated sponsor organizations. Sponsors are responsible for screening and selecting eligible U.S. host families and matching them with students. The sponsor is also responsible for monitoring the students and host families throughout the exchange program. Students accepted into the Secondary School Student exchange visitor program must apply for a J-1 visa in their home country using the Form DS-2019 issued by the designated sponsor.
