Quoting
Mr. Knowitall
The ONLY person who can advise you is the lawyer you hire to advise you. You take the advice of strangers on the Internet at your own peril. Worse, you're still making us guess.
15. Have you ever committed a crime or offense for which you were not arrested? From what you say, Yes.
16. Have you ever been arrested, cited or detained by any law enforcement officer
(including USCIS or former INS and military officers) for any reason? From what you say, No.
17. Have you ever been charged with committing any crime or offense? From what you say, Maybe. (A charge was probably filed in the diversion case.)
18. Have you ever been convicted of a crime or offense? From what you say, No.
19. Have you ever been placed in an alternative sentencing or a rehabilitative program (for example: diversion, deferred prosecution, withheld adjudication, deferred adjudication)? From what you say, OBVIOUSLY Yes.
20. Have you ever received a suspended sentence, been placed on probation or been paroled? From what you say, No. (Unless you are wrong about the circumstances of the diversion program, in which case the answer may be yes.)
21. Have you ever been in jail or prison? From what you say, No.
