Earlier in the thread someone referred me to this document, "Your Payments While You are Outside the United States," and I have read it completely.
From reading the publication, to be honest there was nothing in there that didn't seem reasonable to me, and it is not quite the "Big Brother" scenario that some are making it out to be. It seems mostly to apply to the following situations:
-Special considerations involving non-U.S. citizens who are eligible for payments but living outside the country.
-Living in countries where the U.S. cannot send payments at all. There were only 2, Cuba and North Korea. Viet Nam is no longer on the list.
-Living in countries where receiving payments is restricted, and there are quite a few of those. It may be possible to receive payment in those countries, but special conditions will need to be met.
-Situations involving earning income for work performed out of the country.
-Over on CF there was a dispute about whether or not a bi-annual "proof of life" document was required to be filed. Someone in Panama arguing everyone had to do this, someone in Mexico saying, Nope, never heard of it. There is a list of specific countries where the bi-annual proof of life report is required. Panama is on the list, Mexico is not. Long term expats that have reported their location probably already know whether they need to do it or not, but if you're staying long term in one spot it might be prudent to check the list.
In most situations applying to U.S. citizens you will experience no ceasing of benefits just because you live outside the United States.
Other than that they stress the need to report any "change of address." For those of us who use a permanent U.S. address as we travel about, I don't see how this would apply to us, unless of course we decided to stop our boat and stay for a length of time in one of the countries on the non-payment or restricted list.
My interpretation of the document after reading it carefully is that for my situation there would really be nothing to report just because I am sailing seasonally in and out of the Bahamas/Caribbean unless I decided to drop anchor and stay in Cuba. If someone else can find something in the document that supports a different take on it, please point it out to me. I have no desire to live outside the law, even if I think the law is stupid.
