The United States of America, many people dream to live and work here but how is it possible? Generally speaking you need qualifications or equivalent work experience to get a work permit however here are some of the visa types I am familiar with. From my experience the US is one of the hardest places to get a working visa.
L1 visa: one of the more straight forward visas, this visa is available if you have worked for an international company in another part of the world and can get a transfer to the US office. This visa is eligible for a path to permanent residency.
E3: if you are an Australian citizen this is the visa for you. Renewable every 2 years and available with a job offer. The role does require a labor skills assessment and you need a degree or experience equivalent to get the visa. The hardest part is getting a job offer.
Diversity Lottery: controversial and the Trump government has this on their list to remove but at present is a lottery which takes place once a year in October for Permanent Residency (Green Card). One of the easier ways of getting a visa and I actually know 5 people who have won this. (All had university qualifications)
H1B: another visa which is being scrutinized at present, mainly due to the number of recruitment companies who are abusing this visa and repurposing it. This visa is big in the tech space and is for specialized roles. These positions are supposed to be hard to fill roles and in demand in the US. This visa also leads to permanent residency.
J1- if you were ever contemplating being an Au Pair this is the visa for you. You can participate in the Au Pair program for a year and live and work in the US as an Au Pair. We are currently looking to sponsor an Au Pair as we are looking at child care options once I head back to work at the end of the year. This visa does not lead to PR.
There are other types of visas out there but above are the more common working visas. Please note these are my experiences and information on the visa types above are my opinions. For more information check the US department of state for more information.
