Final 90 Days On Non O

[WaldoPepper]

I have a 1-yr, multi-entry Non O from UK.

1. In mid-May I had to renew my 90 days, taking me until 09 August.

2. The Non O visa itself expires on 26 July.

3. Can I get another (and final) 90 days if I go out and return before 26 July, bearing in mind no. 1?

4. If so, can I get this by doing a land crossing (in my case to Mae Sai)? or

5. Will I only get 90 days by leaving and returning by air? E.g. going to Phnom Penh and returning on 24 or 25 July.

Any advice/help appreciated.

Return at any border before 26th July to get another 90 days.
