dblaisde + sharp: since I deal with these issues professionally, I have noticed recently that more and more Ausländerämter do not accept those international
health insurances for visa and resident permits anymore which do not offer also a long term care insurance (Pflegepflichtversicherung). Most providers of international health insurances can not offer this but I know of one who has a cooperation with Allianz and can thus offer the Allianz Pflegepflichtversicherung together with the
health insurance. On top of that the insurance I am talking about hands out policy documents both in English and German, the latter being important for the German 'crats who even if the work with and for foreigners don't care much about basic knowledge in English language or refuse English documents without translation.
As a retired person, dblaisde, you will most likely also have to proof that your pension is taken care of sufficiently. Nowadays it looks like all ExPats with an age >45years and without an employment contract (i.e. also selfemployed/freelancer) need to show proof for suffiencent pension claims and planning. At least Ausländeramt Frankfurt is pushing that now, but heard the same from others.
In order to make sure you'll get an insurance that will be accepted, employ the services of specialized independent brokers...
I just went through all of this and got a self-employment visa to set up a German office for my American company. Here is a little run down on what happened, that you might find useful
First of all, most of these discussions treat the visa requirements as one size fits all - they are not. A great deal of personal discretion seems to be applied to each individual case. Initially I was going to use the DKV insurance plan, but then when I went to the office to get the application (in September '08), one of the reps there told me that the visa office was starting to refuse this kind of insurance (even though it is a german plan that can be used for up to five years - i think). then I met someone else at random who told me that she had a friend who worked for that company and he told me it would work for sure. I didn't want to deal with an ambiguous situation, so I got the UltraCare Comprehensive policy from Interglobal PMI that provides up to 1.5MM€ of coverage (
www.interglobalpmi.com). When I submitted my visa application/business plan, I also gave them the benefits document from the policy (which they scrutinized for twice as long as all of the other 50pp combined).
After submitting my application in early November, I got a 4 month temporary visa (fiction??) and they told me it would take 2-3 months to approve my visa. Finally at the beginning of February I got a letter telling me I had an appointment for the next week and that I should bring, my US Passport, proof of insurance, and 50EUR. So it took 3.5 months. Knowing they were obsessed with the health insurance, and having a PhD in beauracracy from my time spent in France, I called the insurance company and asked them to send me proof that my insurance policy was good and i had paid and was still paying the premiums. They sent me what I asked for
When I went in, I gave the woman gave the woman the passport and the proof of insurance. After she had examined them she told me (in English and German mixed as I can speak some German, but her English was better) that everything was fine, my business plan was approved, but there was a problem with my insurance.
"what's the problem?"
- you need "unlimited insurance"
"What's that?"
- your insurance expires after one year, it needs to last for as long as you stay here
"This policy is for one year, and after one year I renew it for another year as long as I like"
- But it is a travel insurance!
"No it's not, you can see from that document that I pay every month"
- you pay this much every month?
"Yes you can see, and here is the total amount, that is more than you would pay for a travel insurance"
- OK, that's fine, you can have the visa.
I had a lawyer working with me on this and she told me that they routinely reject applications in which they applicant has a one year travel insurance. But she couldn't tell me why sometimes they accepted insurances such as DKV and sometimes they rejected it. Maybe it has something to do with the German law that says if you make over a certain amount (something like 40,000€) you can have a private insurance, but if you make less you must use the German state insurance.
Anyway, there are a lot of online resources and people you can email to help get answers to these questions. A lot of the information on online forums is sketchy at best. Even what I've told you here, although it worked for me, may not work in your case.
