l need advice re pinay travel to thailand?

l am British and currently in UK. For me, a 30-day visa exemtion can be received upon arrival at the Bangkok Airpoty immigration and l also understand that l can get a 60-day version by providing the Thai Embassy in UK with two photos, my passport and a £25 fee.

However, my fiancee is in the Philippines.

I understand that it is a fact that, provided she has a valid passport and a return air ticket, she can also get a 30 day visa exemption upon arrival in Thailand with no need for any extra requirements BUT in order to get a 60-day version issued in Manila, she has to provide a Certificate of Employment, a bank statement, a letter of invitation (from me??) and pay the 1450 pesos fee together with a completed application form. The complication here is that she is NOT employed and is being financially supported by me from the UK. Thus, a 60-day visa would probably not be granted.

So, if the 30-day option is so simple, she could travel to Thailand and apply for an extension to 60 days once there?

Is that possible and is everything that l have stated factual?
