Very true, the whole H&C system is abused at best, usually by consultants or lawyers who have no hope of winning the case but have no issue collecting the money for it, they should be locked up in prison for the applications they file and receive large amounts of money for.
The H&C provision is VERY useful in circumstances where family is involved. The situation of our friend here is a good example, having a sister in Canada is a positive advantage although coming from the U.S is not the ideal place for H&C. But a viable option nonetheless, IF and ONLY if all other measures have been researched and executed. Unfortunately this theory has been lost on many a crooked consultant. Sorry, just my usual field bashing:)
