US Immigration from Dominican Republic

Greetings. I'm asking for a friend since he does not speak English and I would prefer to get proper advice and avoid him being scammed by folks promising work visas in the U.S. under false pretences. My friend said he has heard of the U.S. offering contract work for foreigners since there has been an issue with owners finding staff to fill positions in various jobs due to the pandemic and folks preferring to receive unemployment benefits since it often pays better than the hourly wage they once worked for.

The question: Is the U.S. really hiring foreign workers to fill current job openings? And if so, where would get accurate and honest info on what companies and how to apply for these jobs if the employers are willing to sponsor immigrant workers to satisfy the work force demand. I thank you in advance for any forthcoming answers.

We finally received our NOA2 today. I know I have to fill out I-134, but after that is completed, do I send that to my fiance to bring with him to his interview?

I m summiting my i130 what kinda evidence should I summit before they ask for anything.

Does anyone knows how to get through USCIS to get a representative ???

I'm going around in cycles.

We had our AOS interview today. The IO was very friendly and it was overall a good experience however he couldn't give the approval because they lost my husband's overseas medical exam at the POE. We did not know this until the IO started to search in our file for the medical. He did issue request for evidence for the medical and i693 form. How long after sending in evidence after an interview should we get an update? He did say he was going to recommend for approval but they just needed the medical to go through with it.
