[Meet the New Boss]

"Mr. Obama, an inveterate journal writer who had published poems in a college literary magazine but had never attempted a book, struggled to finish. His half-sister, Maya Soetoro-Ng, said he eventually retreated to Bali for several months with his wife, Michelle, “to find a peaceful sanctuary where there were no phones.”"

So we have another passport issue for Obama here. How did he stay for "months" in Bali, Indonesia on a US passport under which a tourist visa would only be for 30 days? (Other sources suggest Michelle did not travel to Bali with him.)

Did he use an Indonesian passport to travel to Indonesia to try to write his book?

Right! I forgot about his going to Bali for months to [have ayers write his book]. Michelle could have gone for months too as the spouse of a citizen. They usually get at least “resident” status in their spouse’s country.
