Does a 401k statement fulfill the financial requirements for an O-A visa and is the 60-day family visit extension available for visa-exempt entry?

The discussion revolves around whether a 401k statement can satisfy the financial requirements for the O-A visa from the Embassy in Washington, DC, along with inquiries about the 60-day family visit extension available to those entering Thailand on a 60-day visa exemption. A comment suggests that for those with close Thai family members, it is possible to apply for the 60-day family visit extension after initially applying for a 30-day tourist extension.
