...Quick update: right after I posted I went back to the immigration site & clicked "Home" & the pop-up appeared with the contact numbers. This is the direct link to it.http://www.chiangmaiimm.com/

As mentioned previously though, we called & were informed to mail to the usual address.

Just mailing my 90 day today. I tried checking online for any info. regarding a new mailing address due to the temporary closure of the airport office. Checking the Chiang mai immirgration site I got a pop-up mentioning the temporary closing of the Airport office with a phone number listed  to call for information(Just tried visiting the site again for the link to the pop-up but it didn't show..?? My wife has the screen shot I printed with her with the numbers listed) we called the number this morning & were told to mail the report to the same address as always, so it appears to be business as usual regarding mailing 90 day reports in CM.

...some more info. I was able to cut and paste. I read Thai Visa every day but nearly never post replies/comments. I felt compelled to do so on this thread to help anyone else avoid what I had been through. This is something you need to be careful with...:

             Travel Insurance for US Citizens Visiting USA

...With a short search I found some info. here: http://www.insubuy.com/travel-insurance-for-us-citizens-visiting-usa/ what I was referring to might have been what is written about; which is basically the wording of the policies...& the wording is EVERYTHING. You might purchase something you think gives you coverage but the wording of the contract excludes you & you can bet the insurance company will know that. I did the research I did because, due to an error by the agent I purchased insurance though here in Thailand on a prior trip, left me uninsured. I only found this out because I needed the insurance to pay for the $30,000 plus medical bills I quickly racked up...I wasn't covered. So you can bet I read every word of the policy on my next trip...this is what lead me to realize that there are circumstances you need to be weary of when you are an American travelling to America. It's worth looking into before you simply purchase a policy.

It's been nearly a year since I traveled to the states but I remember there was some very specific rules (or circumstances) relating to American citizens obtaining travelers health insurance when travelling TO America that made it very difficult to be covered (even though many will allow you to purchase)...I wish I could remember the details but can't. I ended up having to purchase separate policies for my Thai wife & child (w/ Thai passport) due to this though. At the time I researched it heavily & this company was the ONLY one I found that I could get legitimate coverage through https://www.sevencorners.com/?a=9D3ED3CD-B4DD-42BF-93B9-772B07BE88FE&z=HWMP8Y3#start . I also read many reviews for this company & they seemed to rate well. If you find the details I'm referring to it would help others to report back. I saved all the paperwork from my policy so I could purchase with this company again for my next travel; so knowing that was all I'd have to do I forgot the details that lead to this company being the only one I could use. I wish I could be of more help but having this link is a good head start.
