Thank you for the links - they contain a wealth of information.
For form 130, which is filed by the USC petitioner for their relatives (parents in my case), doesn’t require the parent’s birth certificate or “no arrest record”. However, it sounds like the visa interview requires a number of documents of the parents. I went through all the tiles in the second link above, but was not able to find specific requirements for petitioning green card for parents - if I’m not mistaken, the information here broadly applies to all immigrant visas. Please let me know if i missed something or didn’t look in the right place.
Would still appreciate input from those who applied for parents - did you need to submit “no arrest records” for parents and at which stage of the process?
Much appreciated!
