Dear Gateradial:
I am sending Scroggs an accurate overview of the US entry requirements for posting, subject to his approval. I will address this question of yours in this. I plan to do it over the weekend when I have time and Scroggs should have it Monday.
The US Immigration Administrative Decisions and the Board of Immigration Appeals Precedent Decisions are available online through the Immigration Service's (now the Bureau of Citizenship and Immigration Services) pfficial government website. However, the internal policy memoranda are not. These are available in two publications "Interpreter Releases" published by West Group and "Benders Immigration Bulletin" published by Mathew Bender. Have a browse through their website and if you have any specfic questions or difficulties you may want to give me an e-mail. Please remebr it is the Bureau of customs enforcement and immigration that makes the determination on admssion into the United States not the consulate. This is regardles of whether you have a valid visa, of any descripition, or not.
I have generally found the US Consulate website very unhelpful and have rarely received helpful assistance from a Consular officer, it is always vague. I suppose these are the joys of international diplomacy. I will try to get an advisory letter from Steven Fischel at the Department of State, he deals with visa policy.
The admission determinations are usually made at the US border and there are very few people who have big enough b.... b... to challenge an admission denial. If the decision to deny admission is a discretionary issue then you will not get anywhere. I don't think I would challenge an admission denial.
I hope this helps.
Campbell
