D4 Chaturthamsa had to be used this analysis, normally 12th, 8th lord gives instability in native place. 4th, 5th and lagna lord shows stability. In general Rahu and Saturn are the karaka for foreign travel. We can use sahamas also, the sahamas like Paradesa Sahama and Jalapatana Sahama will show the points in the zodiac, it can used for cross checking our analysis.

Example:
In you chart, Rahu is in lagna, but it is not the lagna lord here (according to the classics), Lagna lord in 11th house but it with moon, so it can show worries, the two sahamas falls on virgo and capricorn, the 5th and 8th house lord in 12th house

Dasa:
In your chart i can't find any other possible dasa, so we have to stick to Vimsottari dasa, in considering Vimsottari dasa (starting from Moon) current dasa is Moon MD Saturn AD (2008/Dec - 2010/July), here i can't say that you may cross ocean, since the lagna lord is in 11th house with moon, the bhoga falls on 11th house, we have to mind that saturn is the 12th lord also, so we can say that during this dasa the native could have some worry about the foriegn travel.
The next is Moon MD Mercury AD (2010/july - 2011/dec) accoring to sahamas and according to our above calculations we can decide that this dasa may be appropriate for foriegn travel, (why?)
sahamas - Paradesa Sahama and Jalapatana Sahama falls on virgo and capricorn respectively, here the virgo lord is in capricorn, the AD lord is in 12th house and the bhoga falls on the lagna, we should not forget strong Rahu is placed there, so we can conclude that this AD period may be helpfull for the native to have his foreign travel.
