What can I do if my Thai girlfriend is unable to obtain a Schengen Visa for our wedding due to travel restrictions?

Hello everyone, I thank you all for the precious advices I can find on this group page. I share with you my expericence, hoping someone could help.

I have engaged for 2 years to a Thai miss who was able, over the time of our relationship, to visit Italy (I am Italian) 3 times through ordinary Schenghen Visas.

Well, according to the recent italian provisions and EU recommendations, theoretically, Thai citizens are allowed to visit Europe for any reasons without limitations (just 14 days of quarantine). Considering the present scenario, my girlfriend tried to get a new Schenghen Visa from the second half of August until the first week of November. She bought tickets and submitted all the requested documents. Nevertheless, she was not able to get the Visa, due to the uncertainty related to the flight from Europe to Thailand. Only when Thailand revokes the ban and restrictions for commercial flights, Schenghen Visa could be issued. Until then, the uncertainty related to the flights from Europe to Thailand prevent EU Emabassies from issuing Schenghen Visas.

We are really in troubles, because we postponed 3 times our marriage, and, honestly, considering the recent Italian and EU provisions, we arranged everything for the first week of October but we are afraid that we should cancel it once more.

Can please someone gives some advice? We will thank him/her for life.

Thank you for your attention and cooperation.
