Quick question:

My borther in law wants to come here to visit my husband. Would it be better for him to apply to visit and use our address (we are living with relatives) or use his sisters address in Michigan...she owns the home and there are several other family members there. Thanks in advance!

DCF forum has to do with US Citizen filing for a spousal visa when living in foreign country. Has mor to do with "Bringing family members of Permanent Residents to America" http://www.visajourney.com/forums/index.php?showforum=112

Anyway, yes he puts the address where he will be staying at on the DS-156.
