What Alternatives Are Available to a Non-Objection Letter for a J1 HRR Waiver

I'm from Venezuela with a dual nationality. My last country of residency was Venezuela. I obtained a J-1 visa stamped on my passport from Spain. I began to apply for J-1 visa waiver under Non-objection but Venezuelan embassy in Washington notified us about missing a legal employee or agent responsible to sign those letters. Additionally, Venezuelan government and the governmental department of international relations has not replied to 5 letters submitted to request my non-objection letter since 2 years. I would like to know if would be an option to apply under the concept of non-objection letter obtaining independent letters from official department of criminal background, tax and national scholarship from Venezuela in order to demonstrate that I don't have any responsibility with Venezuela and be able to waive the 2 years term.

I hope someone can help me to solve this inquiry. Is important to highlight the difficult situation experienced by all Venezuelans under J visa, nowadays. Venezuelan government is not supporting any Venezuelan living in US.

If you cannot obtain a no-objection statement, you would need to provide (a) a request by an interested U.S. federal government agency, (b) proof that you will be persecuted based on your race, religion, or political opinion if you return to your home country, (c) proof of exceptional hardship to an U.S. citizen (or lawful permanent resident) spouse or child of an exchange visitor; or (d) a request by a designated State Public Health Department or its equivalent.
