Thank you for your response. Having been in the United States for longer than 60 days, your fiancee's petition would be considered to be filed in good faith so it is unlikely that there would be any inquiry as to your fiance's immigration intent.

To that extent and the fact that you and your fiancee wish to marry in the United States, the adjustment of status process would probably be the immigration process with the least hassle and least chance for potential issues because there are more variables which are within your control.

The standard process is outlined briefly below:

Your would file the I-130/I-485 Packet (Petition for Alien Relative) and your fiance could adjust status in the United States without returning to his home country. The entire process takes a little over a year and would require that your fiance take a Biometrics exam and that you and he be interviewed by a USCIS officer who will determine if he married for the purpose of obtaining permanent resident status. If approved, he would be issued a conditional permanent residence card as he would have been married less than two years at the time that you filed
the I-130 petition. The I-130/1-485 packet is found at the USCIS website
at uscis.gov. and the marriage certificate must be included with the green card application.

You and your future husband should file the following forms with supporting documents:

I-130-your petition

I-485-green card application

I-765 -Work permit application

G-325A-biographic form for both of you

I-864-Affidavit of support
