Raju Law or D4U?

Hi,

After a lot of research regarding my application for the NIW, I have cut it down to 2 firms:

- Raju Law - 10k with money back, 85% chances of approval

- D4U - 16/17k with money back after 3rd attempt

Given the price difference between the two and what is at stake, I wanted to get some feedbacks on those two firms.

I had a meeting with D4U, which costs me $50, but for a first consultation Raju charges $300 so I don't think it is worth doing unless I am going with them.

It looks like D4U has a very good ratings but also some very negative reviews saying the people you work with change all the time, you have to re-explain yourself, and it involves more delays. However, per the meeting I had, I thought they had a better support in terms or writing the endeavor and the letters (using templates), whereas Raju doesn't provide as much support and asks you to write the endeavor and letters, and then they review and give feedback.

A bit about my experience: I have an MBA and an MS in STEM from the US, I have a certification, a professional membership, won an MBA case competition and obtained an award at my current company.

The bad reviews from D4U are scaring me out a bit, but on the other hand it feels like they offer better support than Raju which could lead to a more solid case. Any thoughts?
