Some schools strongly recommend online submission, that is, online mode. Some universities stipulate that letters of recommendation can be submitted online or by mail, so you can choose one of two ways.

In general, online submission is recommended. If you choose to submit online, students need to greet the recommender in advance and ask the recommender to provide a common email address. Generally speaking, if the referee is a teacher, it is best to provide his work email address. It is important not to misspell the email address, otherwise it will affect the submission of recommendation letters. After that, when students fill in the online application form, there is a special column to fill in the information of the recommender, including the phone number, address and email address of the recommender. Some schools will ask referees if they choose to submit online, just choose "Yes". If you choose "No", you need to submit it by mail. The recommender will receive an email from the university after the students fill out the form, which contains the URL link and login password. According to the login password, the teacher fills in the recommendation letter online at a specific website and submits it directly online. If you choose online recommendation, you don't need to send a signed recommendation letter or recommendation letter form.

If you choose to mail letters of recommendation, you need to print out n letters of recommendation (at least as many as you want to apply for, and it is best to prepare more copies), and then each letter of recommendation must be signed by the teacher. In addition, most universities provide recommendation forms on their websites. Each school has a different version of the recommendation form, which can be downloaded when applying online. Students should download the recommendation letter form. The upper part of the form is the student's personal information, which is filled in by the students themselves. Signature and date are generally required. After that, give the form to the teacher. The second half of the recommendation form is the teacher's evaluation of the students. After the teacher fills it out, he usually has to sign and write the date. After that, put the signed recommendation letter and recommendation letter form into the envelope, seal the envelope and sign at the seal of the envelope. So the recommendation letter is ready.

There are also a few schools that do not need to submit letters of recommendation, or fill in two or three referees instead. The university reserves the right to contact referees at any time to verify the information. In addition, the school provides a specific e-mail, and referees can write letters of recommendation directly from their own e-mail and send them to the designated university e-mail. In short, letters of recommendation should be submitted according to the regulations of different schools.
