physical address history - Have no idea what one of my addresses was?

[pooj97 89]

I'm filling out the previous physical addresses form for form I-129F but I have completely forgotten what one of my addresses was for when I studied abroad for 6 weeks in Costa Rica at a homestay (resident's home). I have no way of accessing this information because it was 3 years ago and I have gotten logged out of my university email address. The study abroad office will also not give me any information about this. Any advice for what I should do about this? Is general area and city okay to list?

Enter the information as accurately as you can.........If needed, enter "unknown".....yes, enter city and area if that is all you remember.

Try to dig up or find as much information as you can accurately. You can even give a best-guess if you have to. Look for landmarks or other addresses around the area where you lived and try to figure out an address. Or sometimes people reference landmarks instead of an actual address, worst case scenario.
