How does 13. lead to 14.? What is the birth country of the person? Remember there is 10-15 year wait for people born in India ( few years shorter if you are born in china) to obtain a Green Card in EB2 and EB3 category.
Depending on various factors the time between 13. and 14. could very well be between 3 to 20 years (15 years to obtain GC and 5 years after that to obtain citizenship).
