It is not risky as long as you are living together and can demonstrate that your marriage is bona fide.

It's the American way: Pay the least amount of taxed possible. There is absolutely no reason you and your wife cannot file separate returns so long as you check off the married filing separately box. Saving on the taxes owe is an excellent reason for doing so and you can expect no adverse immigration consequences.

It is safer to file jointly than separately, but $650 is a lot of money. If you ran both forms and both of these figures are legitimate (which I am a little surprised it would be that much!) then I would tell you to file the way that saves you the most money, and use that reason as your evidence of why you filed that way. If you have a lot of other documents for your I-751 and naturalization applications, then in the long run, it will not make that much difference in my opinion.
