One of the reason being stuck in Name Check!!!

If you are a member of certain Church, a member of certain societies including Scientific Societies, or club members of "AAA", SAMS, CostCo etc., you didn't declare. You may be stuck in the name check.

As:
I-485 Part3 C. List your present and past membership in or affiliation with every organization, association, fund, foundation, party, club, society or similar group in the United States or in other places since your 16th birthday. Include any foreign military service in this part. If none, write "none." Include the name(s) of organization(s), location(s), dates of membership, from and to, and the nature of the organization(s). If additional space is needed, use a separate piece of paper.

In "N-400", Part 10 B8. Have you ever been a member of or associated with any organization, association, fund foundation, party, club, society or similar group in the United States or in any other place?

Just kidding!!!
