When choosing the transportation mode of USPS, there is no one-size-fits-all cost, because it depends on several different factors:
Customizedpackaging: using your ownpackaging will deliver USPS in the cheapest way, especially for lightpackages transported over short distances.
Size-based rate: If you want to deliver small and heavypackages, you can enjoy the cheapest shipping fee in USPS through MailCubic service, in which the shipping fee is determined according to thepackage’s volume weight rather than its weight.
flat ratepackaging: when transporting heavypackages over a long distance, using the USPS flat rate box option may be the cheapest way to transport USPS.
speed: the faster you want thepackage to be delivered, the higher the delivery cost
service restrictions: different USPS services have specific weight and size restrictions. For example, the Firstclasspackage must weigh less than 13 ounces, and media mail is limited to transporting media and educational materials. Other USPS services allowpackages to weigh upto 70pounds.

After the materials areprepared, it is suggested that you look for the Advisor of VisaServices in the school to helpyou Review them, and then it will be safer to send the materials to USCIS. It should be noted that since the US Immigration Service has several immigration centers in the United States, each center is responsible for receiving OPT application materials from the corresponding state. Therefore,pleasepay attention to the immigration center corresponding to your state. For example, if the international student’s address on I-765 is in new york, New Jersey, Connecticut or Pennsylvania,please mail the application documents to the Texas Immigration Center. Moreover, according to the regulations of the Immigration Bureau, different mailing methods are selected, such as USPS and FedEx, and the receiving address of the Immigration Bureau is also different. Therefore, whether the applicant mails the materials himself or the school helps to mail the materials, the correct mailing address must be determined in advance. After that, I will wait for USCIS to mail back the application result and EAD (Employment Authorization Document) card, usually 2-4 months. You can start working after you get the EAD card (not earlier than the starting working time written on the EAD card)
