Why?
If you’re in the US, you should know this because if you want to apply for a passport, you’ll be required to provide information about your parents such as birth dates and places. If you’re divorced, you will have to provide the same info along with marriage and divorce date, even if it was decades ago. So if you have access to that info, make sure you record it somewhere safe for Future use.
If you’re not in the US, you should know because this information can be difficult for people to get if they never knew one or both parents, or have a bad/non-relationship with them. Or if they had a contentious divorce or an abusive partner. Which is another reason why just leaving the country can be difficult for people who are already marginalized.
Struggled a bit because my grandparents raised me and they’re dead. Not sure all that has to be prefect though. Divorce dates for example, how are they gonna check, call all 50 states and request records? If I can’t readily determine where my grandparents were born, how would the federal government know?
Anyway, this isn’t new, and certainly not a Trump thing because I applied before Biden was out.
