I have an Irish passport and my embassy still supplies affidavit for certifying pensions, my pensions are well over 65,000 baht per month, how does this affect me in the immigration process ,can I apply for my extension as soon as I get the affidavit from the Irish embassy?

I am here on a non O and managed to open a bank account yesterday with Kasikorn just for ease of finances in Thailand ,scan for payment is one reason,so easy to pay with a Thai account
