INSTRUCTIONS

Please read and follow all the instructions very carefully. With the Diversity Visa (also known as Green Card) you will enjoy all the advantages and benefits of a US permanent resident, including health and education benefits, and employment opportunities along with guidance in your new country, orientation sessions and programs to integrate into mainstream American society. Once received you can use it at any time you want to move in the United States or just travel. The visa must be renewed after 10 years.

Although you will have all the rights that a U.S. citizen has in the United States, without a relative or friend in the United States you may find the relocation difficult and expensive due the lack of experience in the American society. Therefore the U.S. Government helps you with the accommodation and offers you along with each visa Health Insurance (Freedom HSA Direct Individual Health insurance for 1 year), Dwelling(Apartment in any city you prefer, 1 bedroom for 3 months ), a guaranteed job(in the field that you are are currently qualified so you can start working even from the first week you arrive in the United States and get paid as U.S citizen. ) and education (for U.S. Students or Higher Education through EducationUSA. It includes transfer to a U.S college or Univeristy so you can continue your educational study. More details can be found at http://educationusa.state.gov/ .)

We remind you that only the visa processing fee ($880) is mandatory and the visa is guaranteed upon receiving the payment.

Accompanying family members(wife/husband, fiancee, brothers, sisters, children, cousins) may be included in the program and their visas will be provided at the same time with yours so you can travel/move together in the same time. However the fees must be paid per person and each member(e.g wife, brother, parents, children, cousin) must pay $880. There is no discount for children.
