Living in the US for a few months on a budget of $800 a month is challenging but feasible, depending on location. Rent for $400 is reasonable in some areas but generally requires compromises, such as living in less desirable neighborhoods or sharing accommodations. Finding a job that pays $800 monthly is likely, especially with IT skills, though competition varies by region. Many minimum wage jobs are available, but they often cater to younger workers or those without experience. Tax implications for foreigners working in the US require understanding visa and work permit processes, which involve sponsorship and documentation. Generally, legal workers pay federal taxes similar to citizens. While some areas have lower living costs, such as parts of North Carolina or Oklahoma, major cities like New York and California tend to have higher rents and living expenses, making it difficult to manage on a limited income. Overall, securing a job in IT or a related field may provide better financial stability than seeking low-wage retail positions.
