E visa vietnam

Hello,

I will arrive in Vietnam the 20th of April (ho chi min city airport). Ik will leave Vietnam by plane in Hanoi after 10 days.
I don't have any means to print the approval letters and Gill in the entry- and exit forms as mentioned above (step 3).

What is your advise for me? Is it possible to enter Vietnam whitout applying for an e-visa before and take care of everything at the airport on arrival?

Thank you in advance!
