Alright: within the next 9 months my sister is leaving for the States to marry her fiance: when she does so, her papers for her landed imigrant status will initiate... which means she can not leave the US for ANY reason even if one of our parents were killed.  
 
Wel at the same time, my girlfriend (soon to be fiance) and myself want my sister at our wedding. Originaly, we thought to do it in June before she leaves but there are too many conflicts to make it work: going earlier than June may be difficult as she will be in college for another month and going into July will not work because my sister leaves as of the 1st...  
 
So... How do we make these 2 weddings work? Any ideas?
