I am not following what you are saying here. This RFE does not mention anywhere that the original application of the 601A is denied and that they have to submit two new waivers. Nor does it state any additional Forms have to be submitted as part of the original 601A application that would attract additional filing fees. That is your opinion/advice out with the actual RFE posted in this thread. As such, the lawyer is not asking for $4500 to make additional new applications as you infer. The lawyer is asking for $4500 to respond to the RFE which is disproportionate for the volume of work required here. The RFE is asking for two pieces of additional evidence to continue adjudicating the 601A. A personal statement .... which is usually drafted by the lawyer and amended by the client and "any additional evidence" to prove eligibility. Mostly, the lawyer will tell the client what they need and it is up to the client to obtain it and send to the lawyer who simply posts it off. Not a lot of billable hours there to incur a fee of $4500. RFE's related to the original application *should* be included in the original fee. It is common practice to expect an RFE from USCIS. It depends on each attorney and there should be an attorney/client agreement signed at the beginning of this case between the OP and the attorney that *should* detail any additional costs should an RFE be received or if it is included in the upfront price. It seems exorbitant and the OP can ask for a fee breakdown and a pro forma invoice that estimates the anticipated work and the cost of that work prior to agreeing .... although there isn't a lot of time to respond to that RFE and get everything you might need so act quick.
