<p>I signed my letter of intent but due to personal reasons I might have to go to a college in Britain. The problem is that I don't exactly know for sure where I am going. I heard that withdrawing SIR isn't that big of a problem but I don't know if I should fill out housing application, etc. </p>
<p>By when do I have to make up my mind? Is it before I pay or would I be billed?</p>
