Travel to North Korea - affect Citizenship application?

[drvikram]

I hold an Indian passport and am eligible for applying for US citizenship (GC holder since 2009). I have the opportunity to visit China and North Korea as a member of medical delegation (not government sponsored) in Dec 2015.

 

1] Any concerns that visit to North Korea can affect my Citizenship application? 

2] I was thinking of applying for citizenship after I return to US or should I apply now, and declare my intention to visit North Korea in the application.

 

Thanks in advance JoeF, Pontevecchio et al.
