The US address fields do not accommodate for International addresses. International address are much longer, and the format is different. Example, their zip code comes before the city/providence, and then country. Just to give you an idea, here's an example of an address I have to fit on an invoice:
Parekh Integrated Services
C/O Parekh Prints, 1st Floor, IIt Bhatti
Italian Textile Compound
Goregaon Mulund Link Road
Dindoshi, Goregaon East Mumbai
100-63 Mumbai
