I believe we mentioned this in another thread, but this is not a way out for you. You're knowingly violating immigration law. If ICA finds out (they DO run checks, more often than you think), you'll both be minimally repatriated, and possibly serve prison time. The law calls for punishment up-to caning for immigration violations, but honestly I don't think you'll have to worry that far
