I am pretty sure that might depend on the country - I don't think all countries have identical laws in this respect.
An alien is not illegal as long as she/he has documentation of status. An alien who is documented to be a permanent resident is not illegal. If the alien does not have and never has had documentation of an immigration status, then that person is an illegal alien.
A permanent alien can stay in a country, but not have resident status and certain privleges.
Absolutely not.
Absolutely not.
If sponsored by a spouse, who is a U.S. citizen or permanent resident, an alien may obtain permanent resident status through the use of a petition naming the alien as a direct beneficiary. Marriage is the tool by which this is done. However, if the marriage is terminated through divorce or annulment before permanent residence is granted, then the alien will not be eligible for permanent resident status by this affiliation. So the answer to your question depends on whether or not you completed your immigration status, if so then you will be seen as a legal resident.
Yup i guess, try ask your mom
The resident would need to wait until becoming a US citizen until filing for residency for the illegal alien spouse.
Sure they can marry, but no felon from a foreign country can gain legal entry into the United States, much less legal status. They are persona non grata.
Yes. You are knowingly harboring a criminal.
A non-permanent resident alien is an individual that holds employment in the United States. They are not a citizen and they do not have a green card.
Yes, however you would have to wait until your spouse becomes a citizen in order to file for alien resident status.
In the UK and Ireland a 'marriage of convenience' as this would be called is illegal.
