The former Wolves star played for the under-21s earlier this week, and played an important role in a win.
His delivery from a corner led to Elliott Lee scoring one of his two goals against Sunderland, and Jarvis feels he is ready for the first team.
He told West Ham's website: "I felt good on Monday. I've trained all last week and was in the squad for the Manchester United game so hopefully I'll be selected for Sunday."
Jarvis scored twice and provided three assists last season, figures he will hope to improve despite the late start to 2014/15.
With two in-form strikers in Diafra Sakho and Enner Valencia, Jarvis will add to an exciting attack.
Relegation battlers QPR are up next and it could be an ideal game for the Englishman to re-integrate himself back into the first team.
He has never quite lived up to expectation since his signing from Wolves two year ago, nor recaptured the form which saw him called into the England squad.
Sam Allardyce has not rushed him back, but having another attacking option on the bench is certainly of huge benefit for the Hammers.
