I was confused about the "qualifying relative," I believe in this case, the qualifying relative would be the US citizen daughter. We might not need the qualifying relative bullet point, if it's been at least 15 years since the activity has made them inadmissible though, no?
This is what I found on the I-601 instructions on page 11 out of 21:
With the application, you must establish one of the following:
A. ...
B. At least 15 years have passed since the activity or event that makes you inadmissible, you have been rehabilitated, and your admission to the United States will not be contrary to the national welfare, safety, or security;
C. Your qualifying U.S. citizen, lawful permanent resident relative (spouse, son, daughter, parent), or K visa petitioner would experience extreme hardship if you were denied admission;
Now, moving on to the drug conviction, I found out this morning and it sounds like the drug wasn't marijuana and was one of the injectable drugs, we don't know which one it was. Does that mean an instant no waiver then?
