You also need to consider that addresses look quite different from country to country. Russian and Japanese addresses are written from the general to the specific, top to bottom. You may need to figure out how to produce these different orderings for forms.

Also, the name of the Russian person above is in the dative case (expressing the idea of 'to the person'). If you asked her to simply supply her name in a separate box, she would probably write Юлия Селиванова, rather than Юлии Селивановой . How will you deal with that?
