I don’t set the standard. As I remember it from 17 years ago when I worked in the field, each year the prez sends a memo to the Department of State indicating regions of the world and the numbers and nationalities of refugees the US might admit in the coming fiscal year. Back then it seemed to be 50-80,000. You might be able to get past yearly totals from the DOS website.
The international system seemed to work fairly well, with aid going to refugees in camps through the UNHCR or other agencies, and various countries pitching in to resettle various numbers. The US was traditionally very generous and played a leadership role in urging others to live up their pledges to share the burden of resettlement and the prohibition of forcible return.
As to my wn efforts, I worked for 20 years helping asylum seekers who were mostly illegals, visited about 30 detention facilities, prisons and jails to interview then and reported on conditions. I contributed to the efforts of many others who urged major changes in the asylum system that came about in the first Bush administration, did some training of US officials charged with deciding asylum claims from certain countries, testified in immigration court a couple of times and submitted written testimony to a Senate committee. This was based on my experience reviewing up to 1200 asylilum claims per year representing several dozen countries, and writing a few hundred opinion letters on the claims. It was a great experience, and I still cherish the thank you letters from refilugees and their attorneys.
As to the homeless, I live in an area that is fairly generous to homeless and am happy to pay the property taxes to make this possible. We all do our part.
