In the application for studying in the United States, university letters of recommendation occupy a very important position, which embodies students' other excellent qualities outside of study, has rich development space and can be carefully planned and written. So how do you submit a written recommendation letter to the school? There are two ways to submit letters of recommendation from American universities, one is online push and the other is paper push. At present, the popular practice is online push, which not only saves time and effort, but also can see the material processing status of the school in time, so it is accepted by most students. When pushing online, students need to click on the recommendation letter in the online application system, and then fill in the email address of the recommender, usually the email address of the alma mater teacher. At this time, don't fantasize about making up your own recommendation letter and filling in your personal email. American universities can see the name of the mailbox in the system. If it is not an email address with the suffix of edu or org, they will generally not recognize it, but it will affect the reputation of students, which is not worth the candle. After filling in the teacher's email, the follow-up work will be completed by the recommender. The recommender's mailbox will receive an email with a submission link sent by the system. Referees can log in to the link to fill in their personal information, and then write or upload their own written letters of recommendation. At the same time, he must fill out a recommendation form, which should be submitted together after all. After the recommender submits the recommendation letter, the applicant will receive the email, and the teacher has submitted the recommendation letter for you. During the whole process, the applicant can't see the contents of the recommendation letter. Some teachers or professors, because of their busy work, will give their written letters of recommendation to students, and let them enter the mailbox to send them online to Weibo. This is very common in domestic universities, but students should honestly fill in the contents of letters of recommendation, because American universities are very strict in reviewing letters of recommendation and are very disgusted with counterfeiting, so even if they know the contents of professors' letters of recommendation, students should not change them without authorization. If the network is not allowed or can't be used, students can use another way: paper push. As the name implies, it is to submit a paper recommendation letter. The recommender needs to print the written recommendation letter in PDF format and sign it. Then, the printed university recommendation letter and the completed recommendation form are sealed in an envelope and mailed to the school. Paper push is not commonly used because it takes a long time to post and can't see the audit results of the school in real time.
