Dream
What do you want to do in 5 years? What about 10? Set that goal and map a path to it. And don't be surprised if you change it in a year -- welcome to the US! 😆
With that identified, or at least ruminating, I would strongly suggest continuing in something akin to, if not the same industry that your experience has. It's helpful to keep moving while you have fresh experience!
As you continue your career, you will find you can use "transferrable skills" to help you maneuver from one job type to another, or even different industries. Your people skills from your IT Sales may work wonders in the services industry. It can also be a great skill for frontline IT Support, or a team manager, which can lead to a director, etc. Don't be afraid to apply for those related jobs just make sure you tweak your resume to fit those changes when you shift!
Research the industry
Meet people in the industry ASAP, ask them out for a cup of coffee and ask them about what skills they use how they got there...learn from their experience. This is what the career advising industry calls an "Informational Interview." It's literally just meeting someone and getting them to talk about themselves so you can learn more about the industry. If they're not too full of themselves, they may also ask about you and help guide you a bit! Maybe you learn that the industry expects credentials you may not have, so you will need to complete a course, a certificate program, or a degree, etc. Or it may be you need to get your foot in the door before getting back to your previous position because the industry expects a different skill set than the one you practiced. All this you will learn
Create application materials
If you make any good connections in the industry, ask them (whom you trust their judgement) to review your resume. Take their suggestions and see what keywords to update or sections to add, remove etc. save a new copy of that resume. Keep tweaking it as you apply to jobs or get more experience.
Apply
Go to LinkedIn or other job boards and apply.
Avoid job scams soliciting you: things that are too good to be true usually are.
Continue to tweak your resume and cover letter for those bigger jobs applications. You should be replicating the language in the job posting. Use their keywords in your resume and cover letter.
Continue to meet with people and grow your network, maybe study something that will help you in the job now so you can learn more keywords.
Resources
Consider the following free resources, many thanks to the US gov.
Bureau of Labor Statistics' Occupational Outlook Handbook General guidance on how to find a job.
O*Net Explore occupations, their typical requirements, statistics, keywords, etc. There are great tools on there.
My Next Move Based on career advising theories and psychology, this tool helps you explore what occupations you may enjoy doing.
Make friends with your local librarians. They can connect you to a ton of resources. Don't get overwhelmed and ask if they can connect you with any free resume or job search workshops. Some libraries host these themselves!
This is my long-winded way of saying there's no easy and quick way that I know of to find a good job -- it's takes work to find work. However, you must do it. Best of luck!
