In my immigration journey, it helped focusing on what all I can do to make the case stronger instead of thinking what the least amount of effort you can do.
What if you end up not liking married life together? The more you visit, the less risk it is for you and your fiance. And more evidence you have for immigration. Is there a big age gap, different ethnical or religious background? If yes to any, you need to prove case more. If all true, you need to work very hard to make case approvable.
