Hi Danny. I "Liked" your post, and was going to ask whether you'd be exiting by land or air. I see from your later post that your question was related to exiting by air. Since you've already decided to forego taking the tour package and instead use the services of a local agent to do your June 3rd visa run, I'll answer your questions here for the benefit of other members and/or casual readers of this thread.
...One of my concerns was that because I’m on a multi entry visa , that when I cross the border, I might not be able to apply online before the existing visa expires on the third.
So I guess my question is- if a person with a multi entry visa where to leave the country before their visa itself expires, can the new visa be applied for and granted before the existing one terminates?
Yes, a person with a multiple entry eVisa, after exiting Vietnam, can immediately apply for a new eVisa. Upon approval and issuance of a new eVisa, the previous eVisa is cancelled. There is no obligation for a multi-entry eVisa holder to wait for the expiry date of their current eVisa. There was a time, up until a couple of years ago, where visitors were able to do what was known as "visa stacking", i.e. applying for and holding chronologically consecutive eVisas. This is no longer possible.
When submitting an application for a new eVisa where it asks for the dates of prior visits to VN, it's important that the most recent (current) visit "until" date shows as the same date which appears on the last "exit date" stamped in one's passport. As an example, if one held a multi-entry visa valid from Jan1st to Apr1st, but the holder exited VN Mar15th, the "until" date must show as Mar15th, not Apr1st.
By exiting via air, immigration will immediately be aware of your departure so there should be no deviation from immigration's stated turnaround of 3 days for approval (an explanation for this can be found here).
because of this confusion, and it ended up being a whole last minute affair with the Thailand tour package, I decided just to do the standard border run through one of the many visa companies that can do it expeditiously at the Cambodian border.
Good choice. Very good choice.
On another note; has anyone here done one of these group tour to a neighboring country trips?
They’re generally not something that I like to do because I don’t like to be on a schedule , but because I wasn’t going alone and Thailand is so foreign to me I thought I would do it because the pricing so reasonable. - @Dannyroc3
There've been numerous complaints from tourists who've had negative experiences with these too-good-to-be-true tour packages. Non-participation in tour activities (read, shopping excursions), not making purchases at preselected vendor locations, etc, have reportedly resulted in tourists being abandoned by the tour operator, the tourist's hotel stays being cancelled mid-trip, and even their return air flights being cancelled. Best avoided.
The people in Thailand are well versed in English, and unlike VN I don't think you'd have much trouble navigating your way while there.
Please keep us updated on your progress through this upcoming border run.
