What are your qualifications? What degrees do you hold in which field from which universities where? What post-master's (preferably doctorate) experience do you have doing what, exactly, how well & how long for whom where? Is this an occupation in short supply in US, and eligible for H1-b or some other type of temporary employment visa?
IF you meet all requirements for some type of employment visa, then you need to find open positions with QUALIFIED employers who have proved there are no Americans qualified & available for that job. Expect to compete with 100-1000 applicants from around the world for that one job! Any job which offers any chance of a temporary employment visa attracts hordes of applicants from around the world. IF you are the person hired, the employer must apply for your temporary employment visa. You cannot apply for any employment visa.
What many foreign workers fail to calculate is US taxes and US cost of living! Gross salaries sound very high compared to countries such as India. However, you must expect at least half of that gross goes to state & federal income taxes, Social Security & Medicare taxes, etc, before you see a penny of money in your paycheck. Then you need to pay rent & utilities, food, household expenses, transportation to/from work, appropriate attire for climate & job, etc. Apartments are typically unfurnished, so you will have to purchase furniture, fixtures, fittings, linens, household equipment & supplies.
Even a foreign student may need to spend as much as USD3000-5000 to purchase a proper wardrobe for climate (e.g. winter clothing is quite expensive), cultural norms, appropriateness. Even purchasing used furniture, clothing, etc. can add up to a great deal of expense.
