a voice from iowa...
funny thing is, iowa has been one of the most liberal states in granting home mortgages to nonimmigrants. i am an example; when the mortgage rates fell really low in mid 2002, my wife and i decided to see if we couldn't buy a house. we were then still in the thick of our AOS process. the realtor, mortgage broker and bank seemed almost dismissive of our repeated reminders that we were not PRs or citizens (a oft-repeated refrain on our part; didn't want to be accused of witholding information at a later stage). the loan broker and bank (in this case, principal financial group based in des moines) were quite aware of H1B status, and were perfectly happy to approve a loan for us at only 5% down.
and we were not the only ones; there were a few other families we knew personally who also applied for and received home mortgages while in nonimmigrant status, including one family in J-status, who had made it clear that theirs' was primarily an investment purchase.
dix is just being a dickhead.
