Can I get a letter from Zimbabwean embassy that I cancelled my Zimbabwean citizenship because I am a British citizen for more than 10years

Hello, Nina -

My condolences on the passing away of your father.

Fixya.com receives questions from people from all over the world. I hope I am correct in guess that your father was a Canadian citizen. If so . . .

I suggest you contact the Canadian Pension Plan directly (by phone will be best) and speak with a real person and ask your questions.

See the CPP contact information here:

Note: Fixya.com is a website intended for asking and answering questions on how to go about repairing things. Personal opinion: For your kind a question, I think it is best to contact the appropriate agency directly.

I am answering from the USA.

Best wishes.

Hello, Joanne -

I am guessing you reside in Australia or are an Australian citizen. I am answering from the USA.

This is the link to the Australian My Gov Contact Us web page:
https://my.gov.au/mygov/content/html/contact.html

I suggest you make a telephone call to the My Gov Help Desk and talk with a person who is knowledgeable. The Contact Us page gives a telephone number for calls within Australia and one for calling from outside Australia.

Best wishes.

Hello, Charles -

You contact the court (municipal, county, or Federal) court which issued the jury duty notice and ask to have a duplicate (replacement) letter sent to you.

Best wishes.

Hello, Cosmo -

You do not state where you are located (residing in Itally and where in the country or residing outside of Italy and stating where that is.) You also do not state what Italian government agency you are calling and where it is located.

See the information here:

From the first paragraph:
(Quote)
IMPORTANT NOTICE TO ALL ITALIAN CITIZENS
Effective March 1, 2016, it is necessary to schedule an appointment, by using the on-line appointment scheduling system to submit a passport application, and following the instructions set forth below.
The new procedure for issuance of the electronic passport requires fingerprinting.Therefore, it is necessary to make a personal appearance at the Consulate. It is no longer possible to request the passport by mail, with the exception of minors under 12 years of age.
(End quote)

Be sure to read all the information on that web page.

Best wishes.

contact the embassy or consul direct
it is your daughters passport that is the item under discussion and not yours

you need specialist legal advice
not a forum page

Wikipedia is a website most helpful, which answers many questions like this. Public Administration is typically the embodied entity that controls and administers the public, their unmet non self-inflicted needs, their taxes, their concerns, and their safety. They are both local, regional, and nationally established to maintain order and civility as well as protect their citizens. This is the role of public administration, though, many with that power begin to abuse it as they or special interest groups with other convictions use the control to their own gain, and even justify it.

The US does not have an embassy in Washington DC.
