I know the letter is a bit long so Thanks a lot for your time !!
Here we go

:
I am currently enrolled in a Master
s of
Political Science
program in XXX. Part of my course
implies requires the completion of an internship starting anytime from July
onward (?). Through this internship I want to achieve two main goals:
1. Working in the research and development department of a well established NGO
, to gain hand
s on experience and pursue my career in this field
(Which field?).
2. Working in Brazil
. as I highly desire to develop my understanding of Portuguese and would like to
have experience
of the country.
If my proficiency in Portuguese is still basic
, I nonetheless have an excellent understanding (written and oral) of Spanish that allows me to
well read
well and understand documents in Portuguese. I am also strongly driven in pursuing my efforts in learning
this language Portuguese (It is better to have Portuguese here since both Spanish and Portuguese are in the sentence).
{which formulation is best ?}
1) I am convinced that I display assets that would benefit to XXX if I was assigned to support the “
Name of a person”.
(Display means to show something. One can display a flag, for example. A better word is "have.") {I am convinced that I have assets that would prove to be a benefit to XXX if I were to be assigned to support the ...
I am convinced that I have assets that would benefit XXX if I were assigned to support the...
You won't support the John Adams (name of a person), you will support the John Adams Foundation.
}
2) I am convinced that I display assets that would make me be a productive member for XXX in the
quality role of subordinate to “
Name of the person”.
Besides my working experience and my academic record
s, my excellent understanding of French and English allows me to contribute immediately to two aspects of this role:
1. Collection and production of materials about the reconstruction of Haiti. Analysis of government proposals.
2. Develop and maintain contacts with overseas partners and organizations.
Moreover, to complete my Master
s I undertook the writing of a thesis, which is due
to in December
of this year. I have chosen to work on the humanitarian response to the Haitian crisis and the post-crisis management. This means that I will dedicate my personal time gathering and analysing data on the matter
, therefore providing
"The organization name" with substantial extra materials.
Furthermore, as I
will progress in my understanding of Portuguese I will
steadily be able to assist in the support of the regional and national programs of "
Name of the organization", or any other requested task.
Finally, in case of a positive response, I will make arrangements to come to Brazil as soon as possible (beginning of June) to undertake intensive Portuguese classes.
Madam, Sir Please be ensured of my high commitment and enthusiasm regarding the above proposal.
If you have the possibility, I would appreciate if you could confirm
that you received good reception of this email. In any case, I will contact ActionAid Brazil office in the course of next week to discuss the matter further.
Yours sincerely,
Thanks again for the courageous that have read the letter till the end

Any comment welcome !
