Well that’s fine too. This forum (in my opinion) is the best resource with experience from all the mods and users like @TBoneTX @Sandra G. and many others willing to assist, explain and simplify any hurdle. To start my process in 2017, I went several years to read thru line by line and that gave me the courage to proceed and here I am today as a U.S. citizen all thanks to this forum.
My best wishes to your friend, with faith and perseverance it will surely be fine one day.
Have a blessed day 🙏🏽
