<p>I have researched this from a Canadian perspective, which may be different for prospective students from other foreign countries. I have also worked in the federal government on immigration, and it’s safe to say that if an interviewer is even suspicious of mis-truths or lying, they will deny your application, no matter if it is relevant to the application or not. </p>
<p>While it is impossible to know all the questions that may be asked in the interview for your visa application, it would probably be safe for you to say that you are focusing on this current application and it would be presumptuous to speculate beyond that. </p>
<p>On the other hand, there is nothing wrong for you to say that your ultimate goal is to obtain a law degree, as there are usually two years of university required before you can even apply to any law school. Or some law schools may even require you to have a undergraduate degree. </p>
<p>The first degree is a natural stepping stone to a law degree, so it shouldn’t matter that you want to pursue both. That shouldn’t affect a decision to receive a student visa - but you should research that issue in your own country.</p>
<p>If your intent is to ultimately work in the US, once you are in possession of a US student visa, you can apply to work in the field of your studies for up to one year following graduation. After the year of work, your visa expires and you would have to return to your home country.</p>
