do not understand if you are talking about the same. Re entry is just handing your passport with the visa stamp in it and passphoto. In subarnabumi they even do not require photo . They make a photo and that is all. Five minutes in and out.
i got a ltr visa , pensioner in februari. But could submit two years already. But you ar e right, just starting receiving pension makes it impossible to have 2 years statement. Just contact the BOI . The two ladies (half a year ago) are utmost helpfull .!
