Hi, I will be travelling with my Mom (who holds a US passport) and myself Malaysian passport. We will travel from Malaysia to Siem Reap then only to Hanoi. By the time we reach Hanoi Airport will be 11pm at night. Will I still be able to help her apply the VISA ON ARRIVAL ? If yes, all I need to do is just help her submit her passport details online , wait for the reply from Myvietnamvisa on email. Get my mom to have the visa photos. The rest we will just wait until we reach Hanoi airport to proccess. ? Am I right on the above ?
