Thanks Robert - Jomtien is my immigration office. Ive downloaded the requirements from the Pattaya Expats Group - who have a nice summary - but not info on when :)
If you use the immigration app on an iPhone you can register as a tennant - (individual not duristic). Not sure if android app is the same. Have a copy of the landlords blue book and tenancy agreement and your passport to upload and you should be ok to register ( that is what I attached to my registration)
