Just commenting on the L2 and visa matter... L2 is just the status that you are in (similar to H-1B). How long you can stay in the US is determined by the date on the I-94. How often you can re-enter on a visa depends on the single/multiple entry on your visa stamp. If you happen to have a single entry visa, then of course you would need to make another consular visit to get a new visa if you wanted to come back to the US. Remember, the I-94 date trumps whatever duration you have on your consular visa stamp. If the date on your I-94 says leave tomorrow... then, in most cases, that is the best course of action to take.
