No. I don't know exactly what "college certificate" means in this case, but only certain documents are acceptable legal proof of the right to work in the US, and they don't include anything that might possibly be referred to as a "college certificate".
You can generally use a school-issued photo ID as proof of identity, but it doesn't constitute proof of eligibility for employment, and BOTH must be presented to an employer for them to legally hire you.
Yes, but you would still lack the legal right to work
You can sponsor him/her for a work permit. I am not sure if you have to lie and say that he is still in his home country or not (you may have to). Bear in mind that work permits for uneducated (no college degree), unskilled workers are nearly impossible to get.
If they have a green card, they can work.
If you mean is it legal to HIRE a legal immigrant, then yes, certainly. It is ILLEGAL for employers to prefer US citizens over legally admitted immigrants. everyone legally allowed to work in the USA competes with every other legal worker. The ILLEGALS must sit out the competition and not work anywhere.
I believe you are asking if it is legal for an employer to hire a legal immigrant over a American citizen. By "legal immigrant," I assume you mean one who is authorized to work in the United States. Yes. As long as the person hired is legally authorized to work in the United States, his citizenship is irrelevant. Keep in mind that it is illegal in many jurisdictions for an employer to discriminate against a potential employee on the basis of national origin.
If he is an immigrant but is legal to work within the country and has a residence there then surely you owe him all obligations normally given to a normal worker.
no, only when you have a certificate for your work on that time.
Simply stated, No.
You have to marry her in order for her to be able to keep a legal occupation in the United States.
A college certificate is a document acknowleding the completion of a specific course of study on par with collegiate level academics. A certificate focuses on one very specific area of study as opposed to a field of study covered by a longer associate or bachelor degree program. Certificate programs are offered in a variety of different fields. Certificate programs are designed to prepare a person for a very specific work field. The study time required to gain a college certificate is often one year or less. Most college certificate programs require the completion of six or less courses in order for the certificate to be issued.
If an immigrant refuses to sign paperwork related to their deportation, it may lead to a prolonged legal process. Authorities may still proceed with deportation if the individual does not have a valid legal claim to remain in the country. Additionally, refusing to sign could result in detention until a resolution is reached. It's essential for the immigrant to seek legal counsel to understand their options and rights in such situations.
The proof of legal right to work required for employment is typically a document such as a Social Security card, birth certificate, or work authorization permit that shows an individual is legally allowed to work in the country.
