If I get married to a US citizen, can I go legally to the US?

In order for a foreign national to enter the U.S., he or she must have authorization to do so in the form of a visa. Generally, when a foreign national becomes married to a U.S. citizen, the couple can succeed in consular processing in the Immediate Relative visa category so that the foreign national spouse may enter the U.S. and ultimately become a Lawful Permanent Resident (i.e., get a "Green Card"). Of course, there are many other details addressing eligibility for consular processing, and it would be wise for you and your U.S. citizen spouse to consult with an immigration attorney who, after learning all of the relevant details, would be able to advise you about eligibilities, options and strategies and who could offer legal representation in the often quite complex application process.
