Your old priest is definitely wrong. No doubt about it. The Congregation for Divine Worship issues Instructions from time on time on the correct procedure for the celebration of mass, including the question of communicants receiving kneeling or standing and on the tongue or in the hand. The two most recent Instructions of this kind were Eucharisticum mysterium in 1967 and Redemptionis Sacramentum in 2004. In the matter of kneeling/standing to receive the Eucharist, there were not one but two significant changes from the 1967 Instruction to the one that followed in 2004.The two changes mutually reinforce each other:
***Dropped: ***The faithful should willingly follow the manner of reception indicated by the pastors so that communion may truly be a sign of familial union among those who share in the same table of the Lord (Eucharisticum mysterium, No. 34).
***Added: ***it is not licit to deny Holy Communion to any of Christ’s faithful solely on the grounds, for example, that the person wishes to receive the Eucharist kneeling or standing (Redemptionis Sacramentum, No. 91).
You may point out to your priest, if you choose to, that he is eleven years behind the times. He is still following Eucharisticum mysterium, in which the priest’s decision overrode the individual communicant’s preference. Since 2004 it has been the other way around.
In case you’d like to print out the relevant bits of Redemptionis Sacramentum — or even the whole thing — here’s a link for you:

One last point. In the event that the priest should try and drag the USCCB into the argument, remind him that a national bishops’ conference, whether in the United States or anywhere else, is not empowered to rewrite an Instruction issued by the CDW.
Good luck!
