E-Visa Vietnam

Hello dear organization :)

I’m going to flight to vietnam: I already booked my tickets and they are saying that i’m leaving frankfurt on the 28th of august and i’m landing in vietnam on the 29th of august 2018.

Now my questions: 
1) When applying for the E-Visa, can i state that the Grant E-visa is valid from 28th of august, while my intended date of entry is actually the 29th of august? Or do i have to state the Grant Evisa is valid from the 29th of august, because that’s the actual day, i’m landing in vietnam?

2) for the Permanent residential address, is it enough to state the country? or do i have to state my complete adress?


Thanks a lot!
