No. He or she must still apply for permanent resident status and then citizenship as required by US immigration laws.
Nobody, not even a Venezuelan can become a US Citizen just by marrying a US Citizen. But it is by far the easiest ways of getting the citizenship. A person marrying a US citizen will be first granted with the conditional permanent resident status. After being so for 3 years, they can file in their citizenship application, if they satisfy all other eligibility conditions.
Can an illegal alien who was deported and barred for ten years come back sooner by marrying an us citizen?
You've got to be kidding. Breaking the law is not the path to citizenship or permanent residence, neither is marriage.
Unfortunately, an illegal alien can not become an US citizen if they have been deported before. If they have a felony, they can't become a US citizen either.
