You must qualify to file for an I-130 in the US. Not everyone does, and in some cases doing so can be considered fraud and result in being deported and banned from re-entry into the US for a period of time. If you attempt to file and you do not qualify your legal status in the US can be placed in jeopardy. J1 Visa holders will almost always require a waiver and should consult with an immigration lawyer or the USCIS for more information. If you have any doubt, consult an immigration attorney.

If your fiance/fiancee came to the US on a tourist visa with the intent of immigration and marriage, and you are not yet married, then he/she should return to his/her home abroad, and the K-1 visa should be filed (using an I-129f) instead of the I-130 to avoid a denial, deportation, or even being banned from re-entry to the US.

If you are already married, and your spouse came to the US on a tourist visa with the intent of immigration and marriage, then he/she should return to his/her home abroad, and the I-130 (or along with an I-129f for a K-3 Visa) should be filed with the relative outside of the U.S. to avoid denial, deportation, or even being banned from re-entry to the US.

The above conditions are serious and can result in the separation of families for many years if not taken seriously.
