Thanks very much for the reply. Here are his exact words:
"Recently, National Visa Center does not accept the assets as the financial resources to support the intending immigrant, especially when the petitioner is also outside of the States."
Between my wife and I we have over 100k in assets which could be easily converted to cash in less than 1 year and we have no dependents. Some of our assets are here in Germany, some in the US, and some in Korea. As well I have a 401k but I was told that didn't count.
I believe he's drawing on his own experience so I'm wondering if anyone has seen this recently? Or maybe I should push back on him to do a bit more research. Time is on our side for the moment as we only just filed the application a week ago.
