The 28-year-old Lahiri, who finished tied sixth in the first event last week, himself feels that he has got the 'job done' at River Run, the second of the four-event Web.Com Finals series.
Officially he will get his card after the final event of the series in two weeks time.
Lahiri, who played only 12 events on PGA Tour this year, will be able to play more events in the coming season. He will become the second Indian after Arjun Atwal to hold a PGA Tour card, though Atwal remains the only Indian to win a title on PGA Tour.
After picking up USD 34,750 in the first event from his sixth place finish last week, he added another USD 15,000 from his 16th place finish this week.

The total of USD 49,750 places Lahiri seventh on the Web.Com Finals Money List, which offers the Top-25 a card.
Lahiri, who started the final day at seven-under and in tied 20th place, began with birdies on first and third. Steady pars over the next seven holes meant he was closely approaching his goal.
Once again Lahiri's grit was on display as he still managed only 50 per cent fairways and needed more than 30 putts. But he scrambled very well.
