The more important question is if they plan to be outside the US for 10-11 months, they need to worry about maintaining their green card status and not abandoning their status since they are out of the US for more then 6 months. They have to apply for a re-entry permit 90 days prior to their planned extended departure from the US as LPR's to be able to maintain and retain their green cards. On the renewal issue of their green cards, if their green cards expire in March 2014, aren't they eligible for naturalization at this stage? That may be the better option. The fingerprint notice comes pretty early now, a few weeks after applying especially if you apply online for a renewal. Once a receipt is issued, they can also apply for a stamp in their passsport with USCIS as a temporary extension of their I-551 Green Card while the renewal process is pending.
No. They can seek reentry permit instead.

I share Mr. Calehr's concern ... a 10 month trip is not, I repeat NOT a good idea.
Although Mr. Segal is also correct, a Re-entry permit will help ... I suggest filing for naturalization.
In that way they can travel on US passports and not 'lose' the residence they've accumulated ... which will happen if they take a trip of over 6 months.
