If you are an American citizen and you want your foreign fiancé(e) to travel to the United States to marry you and live within the U.S., you must file Petition for Alien Fiancé(e) in the United States.

You must file the Petition for Alien Fiancé(e), Form I-129F, next to the Department of Homeland Security's U.S. Citizenship and Immigration Services (USCIS) office that serves the area where you live. See the Department of Homeland Security's USCIS Field Offices for information on where on earth you can file the petition. Note: You cannot file this petition at an embassy, consulate or U.S. immigration office in a foreign country

After the USCIS approves the petition, it sends the petition to National Visa Center for processing, prior to sending it to the embassy or consulate where your fiancé(e) will apply for a K-1 nonimmigrant visa for a fiancé(e).

The consular section at the embassy or consulate where you, the fiancé(e) of an American citizen, will apply for a visa, will convey you about any additional specific requirements that you need to fulfill to complete your visa application, such as where on earth you need to go for the required medical examination. During the interview process, an ink-free, digital fingerprint scan will be taken. The following is required:

* A passport valid for travel to the United States and beside a validity date at least six months beyond the applicant's intended period of stay surrounded by the United States (unless country-specific agreements provide exemptions).
* Birth certificate
* Divorce or death certificate of any previous spouse for both the applicant and the petitioner
* Police tag from all places lived since age 16
* Medical examination (vaccinations are optional, see below)
* Evidence of financial support (Form I-134, Affidavit of Support may be requested.)
* Two Nonimmigrant Visa Applications, Form DS-156 (A Form DS-156, prepared contained by duplicate.)
* One Nonimmigrant Fiancé(e) Visa Application, Form DS-156K
* Two nonimmigrant visa photos (each two inches 50 X 50 mm square, showing full face, against a light background)
* Evidence of a fiancé relationship
* Payment of fees, as explained below.

The consular officer may ask for additional information according to the circumstances of the overnight case. Documents in foreign languages should be translated.

Take clear, legible photocopies of civil documents, such as birth and marriage certificate, to the interview. Original documents can then be returned to you.

United States immigration law requires immigrant visa applicants to obtain correct vaccinations prior to the issuance of an immigrant visa. Panel physicians who conduct medical examinations of immigrant visa applicants are required to verify that immigrant visa applicants have met the vaccination requirements. See IV Vaccination Requirements for the roll of required vaccinations and additional information.

As a fiancé(e), you are not required to fulfill this requirement at the time of your medical examination for a fiancé(e) visa. However, you may want to do so. These vaccination are required when you adjust status following your marriage.

After getting the fiancé(e) visa, your fiancé(e) enters the U.S. through a U.S immigration port-of-entry. The U.S. immigration official give your fiancé(e) instructions on what to do when he/she enters the United States. You must get married within 90 days of your fiancé(e)’s entry into the United States.

After wedding ceremony, your spouse must file Form I-485 Application to Register Permanent Residence or to Adjust Status with the USCIS office that serves the nouns where you live in the United States. You must fill out the Affidavit of Support, Form I-864, beside the USCIS for your spouse's application to become a lawful permanent resident (LPR). See Permanent Resident at the Department of Homeland Security's, USCIS internet site.
If you are thinking of marrying a Mexican citizen, you will own to prove how you met and how long you have been together and prove you have sufficient income and assets to support your boyfriend, and provide a guarantee of his support ($30,000, as I recall) contained by order to get him a fiance visa. If approved (it takes nearly a year), he can enter the US and you two must marry within 90 days and then you file for a spousal visa. After a year or so, he can take work authorization, then apply for a Social Security number and apply for jobs. You will have to support him minus his working for at least a couple of years, so you need a good income! Eventually he can carry a green card, then apply for citizenship.

How did you two meet? Is he living in the US? If so, what style of visa is he on? Has he ever violated US immigration laws? You cannot get him a fiance visa if he is in the US. It must be obtain while he is in Mexico. Also, if he has been here criminally, you cannot "legalize" him by marrying him. As soon as you apply for his visa, you expose his illegal status and he will be deported and barred from re-entry.

The process is long, complicated and expensive. It will transport 5 years or so for him to eligible for citizenship -- assuming he has never violated US immigration laws and he lives in Mexico.
you would be better off a moment ago move to mexico and stay there with your bf..
Do your homework and go to www.uscis.gov , he have to be a resident and then apply for citizenship.
