Why MUST you request your DSO signed I-20 ship as soon as it is ready and who is responsible to request the I-20?

a. It is required you have an endorsed/signed I-20 when Customs and Border Patrol or police ask for it
b. We only keep an unsigned digital copy and cannot sign an I-20 after the fact
c. It is against U. S. regulations to send digital (signed or not) DS-2019s and must treat I-20s the same
d. You will need all signed original I-20s to make copies to apply for OPT, STEM and H-1B in the future, so get them now!
e. It is the student’s choice to request each term, however, we cannot go back retroactively to provide past copies
f. We can only provide a signed copy of current I-20 and if changes occur from previous semesters that information will not show
g. The original endorsed I-20 signed by a DSO will be destroyed after 30 days of issuance if not picked up, and it cannot be replicated
h. The cost to have I-20 shipped may go up at any time
i. All the above
