Once you receive the approval letter issued by Immigration Office (even after you apply and we submitted your application the Office), you cannot modify any information stated on the letter. In case you need to change these details or plan to arrive earlier than the approved date, you have to to reapply for a new visa approval letter.

No, you cannot. Vietnam visa on arrival is applicable to air travel only since the visa applicants must get visa stamped at the arrival airport in Vietnam. If this is the case, you are recommended to contact the most convenient Vietnam Embassy/Consulate to apply for a visa.

Along with Vietnam Visa Application Form, Photos and Arrival Letter are compulsory documents to get proper Vietnam Visa when being in Vietnam Airport. 

Therefore; if you forget to bring photos or Arrival Letter before arriving Vietnam Airport, you may have to pay extra money (around 2 – 5 USD) for being taken photos by Immigration Officers & a lot of money to print out Arrival Letter right there.
