I'm absolutely not a lawyer, so may be mistaken, but the fees for I-129 / DS-160 are not explicitly mentioned anywhere. Instead the fee seems to be an entry fee, which is orthogonal to the actual visa (meaning ; you can have a visa but not be granted entry, or maybe be granted entry under a different program but then with no lawful work permit).
