country_boy-- Pretty much everyone here is right. This is a matter of how the question is worded versus what the question really is trying to ask. You could argue that on OPT you are authorized to work for any company as long as the work is related to your field of studies. So you should be able to chose "I am authorized to work  for any employer". However, that's not the intent behind the question. The intent is to know whether you are a citizen or a legal permanent resident or not (When I was in your situation I called some of the companies and asked them how I should answer the question. After talking to 4-5 HR people I came to know what the intent behind the question is). You should chose "I require sponsorship to work in this country" because the fact is that after that one year you will require sponsorship. However, like someone said above, if you do that you might not get any interviews at all. My response is based on my personal experience. I am not a expert on this matter.  Having said that, if you decide to choose the 1st option I would strongly advise you to contact the HR department and let them know that you are legally authorized to work for any employer for the next one year. Obviously, if the HR person doesn't understand what you are talking about they might just ignore your application and move unto an America (especially in this economy).
