It seems the State Department wrongly believes that marriage to a US citizen is often used by J-1 visa holders to bypass the requirement, that is why they are dragging the hardship waiver process to take longer than the requirement itself, it's a form of punishment for those who actually face severe hardship and cannot return home with their families. They might as well just stop allowing waivers under this category. There is no other reason why all other waiver categories are processed faster than hardship to a US citizen, even persecution waivers are processed faster. You would think that the Biden administration would prioritize the wellbeing of its own citizens and their families, but no, they decided to prioritize politics and program and policy considerations. They have not even posted the statistics for the past fiscal year, my guess is that there is a shocking increase in the rate of denials of hardship waivers by the DOS. it's a desperate time.
