Tourist Visa For 30 Days Only?

My Kenyan girlfriend arrived in Thailand on October 5th. She has been numerous times before and always gets 60 days on her single-entry tourist visa that she obtains from the Thai embassy in Nairobi.

This last time she got only 30 days! I assume it was a mistake (airport just open, new rules etc.) so off we are to the immigration bureau to have the stamp corrected.

At two desks she is told this is NOT a mistake and part of the new rules. However, the website of Thai immigration still mentions that people get 60 days on tourist visas? So what is it?

Luckily she can extend for 30 days (so they said...) so it is not so bad but does anyone know about new rules for countries that are not allowed 30-day stamps on arrival?

Thanks for any info,

Kipara
