The mother of 14 has posed naked for Closer magazine, shot a solo adult film and accepted a stripping job in recent months.
She had previously filed for bankruptcy with over $1m (£640,000) in debt.
"I am so grateful for all the amazing opportunities that have come my way and I am finally in a stable situation," Suleman told E! News. "I will keep working as much as I can to take care of my children."
"Yes, Nadya has been off welfare for a month now," Suleman's rep added. "Nadya's financial situation has changed dramatically in the past few months and between her endorsements, movie and appearances she is financially stable for the first time.
"She will not be doing anymore stripping appearances as she only did it to promote the release of her DVD. Nadya has several adult bookstore appearances scheduled to promote her movie Octomom Home Alone. She also has her new single set to release in August, 'Get On The Dance Floor', and she will be performing her single in clubs."
